NANNO NEWS March 2005

Nanno News is the newsletter of the International Nannoplankton Association.
Editor Jean Self-Trail, HTML conversion by Jeremy Young.


Hello everyone and happy New Year! I hope 2005 finds you all healthy and happy. With this issue of Nanno News, we start a new format that I hope everyone agrees is more economical and easier to access. Instead of producing a paper copy with every volume of the JNR that is published, Nanno News will instead be a web-based newsletter. This move was made for several reasons: 1) its cheaper! and 2) almost everyone has at least sporadic access to the Worldwide Web now. The newsletter will still be "published" on the same schedule as the JNR (an issue in January and an issue in July). Occasional extra issues may be "published" if warranted.

This issue covers a variety of topics, including a summary of INA10 (for those of you who were unlucky enough to miss it!), the specifics on a very important upcoming meeting for micropaleontologists, and a very interesting synopsis of some biostratigraphic interpretive software available to the microfossil community. I'd like to welcome David K. Watkins as the new INA President and thank Woody Wise (the outgoing President) for all of his hard work and patience. Additionally, we should all take the time to welcome Alyssa Peleo-Alampay and Guilliana Villa as our new council members at –large. As a reminder to those who missed INA10, the group voted to raise dues to $50 US dollars a year for professionals and $25 US dollars a year for students in order to cover rising publication costs; a hard decision to make, but a necessary one. By now, however, we've all had a chance to look at the new JNR and the results are phenomenal! I have a complete set of the JNR sitting on a shelf in my office, and it's interesting to see the change in styles and quality as the Journal has morphed from a simple newsletter to a Journal poised to take on the Science Citation Index. Thanks to Jackie Lees for her tireless efforts and hard work!

So, with no further adieu, I invite you to sit back and take note of the comings and goings of our colleagues around the world. Enjoy!

Industry News

Those of us employed as biostratigraphers in the oil and gas industry are routinely asked to provide results with much finer stratigraphic resolution than what is possible with conventional techniques. Increasingly we rely on statistical software to help us with correlations. This column will continue the subject of biostratigraphic interpretive software that I started in a previous column. Once again, this is not a commercial, I'm not advocating one or another available software package. I'm just informing you of what's out there. Tony Gary was kind enough to provide a synopsis of the IPS biostrat workstation.

The Integrated Paleontological System: A Workstation Environment for the Analysis of Biostratigraphical Data

The Integrated Paleontological System (IPS) is designed to give the biostratigrapher an interactive workstation environment for the rapid analysis of biostratigraphical data. IPS is compatible with Microsoft's® Windows 95, NT, Windows 2000 and XP operating systems, and will readily accept the data file formats from commonly-used biostratigraphical data acquisition/storage applications (e.g., StrataBugs and BugWin), as well as csv formats from Excel®. The system is composed of four primary analytical modules: Range Chart, Matrix Analysis, Stratigraphy and Multi-well Analysis.

The Range Chart module is a digital version of the paper-range charts that have been the mainstay of biostratigraphic analyses. In this module, the biostratigrapher can quickly navigate the range chart by "point-and-click", and display a variety of standard curves, such as total abundances and diversity, as well as more specialized curves including ratios, estimated paleowater (for benthic foraminifera) and faunal-break analysis. The faunal-break analysis highlights sample depths where assemblage changes occur that are due to factors other than differences in sample size, as can result from dilution by sands. This approach helps to locate subtly expressed horizons that can be important in sequence stratigraphic interpretations, but are easily overlooked based on inspection of the range chart alone. In the Range Chart module, external data such as petrophysical, stable isotope or synthetic seismic, can also be displayed to assist in the interpretation of the biostratigraphical data.

The Matrix module provides a new way of looking at biostratigraphical data that complements the traditional range chart. The "matrix" is an association matrix of a well or section relative to itself or relative to a second well or section, in which the association or similarity of every possible sample pair is calculated and represented as elements of the matrix. The columns and rows of the matrix are sample depths, and each element of the matrix represents a sample-pair similarity value that is mapped to a spectrum of colors ranging from dark blue for the lowest similarities to the red for the highest. This matrix color-map display allows the biostratigrapher to very quickly find sample intervals with similar assemblages, recognize a repetition in an assemblage that may result from depositional cyclicity or thrusting, and evaluate how rapidly an assemblage changes from sample to sample. This data analysis approach has been quite effective in enabling the biostratigrapher to very quickly produce an initial interpretation in a sequence stratigraphic context that can then be validated using the Range Chart module.

The Stratigraphy Module allows the biostratigrapher to evaluate, modify, cull or add stratigraphic events, and crossplot a well's events relative to another well, a time scale or a composite event sequence. A correlation line can be created within the crossplot using either a spline function or manual line segments, and from the correlation line events can be projected between wells and a depositional rate curve produced.

The Multi-well Analysis Module is a multiple-well interpretation environment in which the analytical results and interpretations produced from the modules discussed above can be loaded and correlated between wells. The biostratigraphically-derived curves (e.g., total abundances, paleowater depth, ratios, etc.) produced within IPS can be displayed for each well along with externally generated curve data, such as petrophysical data, to help fine-tune the correlations based on stratigraphic events.

The modules are integrated with one another so that a sample depth or taxon selected in one is also selected in the others. All data manipulations that can be displayed as curves in the Range Chart module can likewise be displayed in the other three modules. The IPS software is available for commercial, government and academic use from Tramontane, Inc. (

Recent Graduates

Congratulations are in order to several INA members who have recently completed their Ph.D's.

Elif Eker Develi received her degree from the Middle East Technical University, Institute of Marine Sciences, under the guidance of Assoc. Prof. Ahmet Erkan Kideys, Prof. Dr. Temel Oguz and Assoc. Prof. Sukru Besiktepe. Her PhD was titled “Nutrient effects on phytoplankton dynamics with special reference to the atmospheric deposition in the northeastern Mediterranean”. She focused in particular on Emiliania huxleyii. She is currently looking for post-graduate employment, so please don’t hesitate to contact her about any potential jobs.

Elena Colmenero Hidalgo was awarded her PhD Thesis titled Respuesta de las asociaciones de cocolitoforidos a los cambios climáticos del Cuaternario final: reconstruccion de la dinámica superficial y climática del Mediterráneo occidental y del mar de Arabia” (Response of coccolithophore assemblages to Late Quaternary climatic changes: reconstruction of the Western Mediterranean and the Arabian Sea surface and climatic dynamics). This PhD Thesis was carried out in the Paleontology Area of the University of Salamanca (Spain) under the supervision of Dr. José-Abel Flores Villarejo and Dr. Francisco J. Sierro Sánchez and it was defended on June 7th, 2004. It was written in Spanish, although several chapters have already been published in international journals and Elena expects to do the same with the others in a short interval.

The PhD. research was focused in the study of the fossil record of coccolithophore populations of the last 280,000 years. The objectives were mainly 1) to provide a new approach to existing paleoceanographic reconstructions, and 2) to investigate and verify the paleoecological meaning of coccolithophores. Five sediment cores were studied with this purpose: three of them (located along the Iberian Margin) provided a high-resolution record of the last 50,000 years, whereas the other two (recovered in the Arabian Sea, off the coasts of Oman) contained material deposited along the last three climatic cycles. This selection allowed the study of the same coccolithophore taxa in different temporal and geographic contexts. The data obtained allowed to propose new paleoecological meanings for several taxa and to demonstrate the usefulness of coccolithophores as proxies in paleoclimatic and paleoceanographic reconstructions at both orbital and suborbital timescales.

In November 2004, Elena joined Dr. Ian Hall's Paleoceanography team at the School of Earth, Ocean and Planetary Sciences of the University of Cardiff (Wales, United Kingdom) as a Postdoctoral Research Associate. There she is to work mainly in stable isotopes and planktic forams on Last Glacial high resolution records from the northeastern North Atlantic, although she is also to continue working with coccolithophores in some of the cores stored there. She also hopes to improve her English (and maybe try to learn some Welsh!).

10th Conference of the International Nannoplankton Association, (INA10)

August 28th - September 4th, 2004, Lisbon, Portugal

Host: University of Lisbon, Portugal
Convenor: Mario Cachao,

INA10 was held in beautiful Lisbon, Portugal by Mario Cachao and his able team of students, scientists and staff. Pre-meeting festivities included beach games and football (an INA first) and although I was unable to attend, I understand that the INA boasts some true athletes (as well as some athletic wannabes!). The meeting social gathering was grand, and I enjoyed meeting with old friends, sipping excellent Port (a particular favorite of mine) and talking late into the night.

The meeting itself provided a lot of stimulating and interesting topics for discussion. The opening session covered biostratigraphy and evolution, and included such topics as Lower Pliocene biodiversity by Daniela Crudeli (and others), evolutionary trends in the Rhomboaster-Tribrachiatus lineage (Simonetta Monechi and Eugenia Angori) and the relationship of palaeoenvironment to evolution in Upper Jurassic Watznauerias, by Fabienne Giraud and others.

Paleoecology was a hot topic, and talks included examination of living coccolithophorid communities (Jose Gravalosa and others) and Yuichiro Tanaka (to name a few), as well as examination of fossil communities (Alexandra Duarte-Silva and others). The paleoceanography, climate proxies and global change session covered oceanic anoxic events during the Late Cretaceous (Emanuela Mattioli and Bernard Pittet; Paola Tamagnini and Elisabetta Erba), the Messinian salinity crisis (Simona Giunta and others) and the response of calcareous nannofossil communities to El Nino events (Bianca De Bernardi and others; Daniela Crudeli and others).

Recognition of different calcification modes in the haploid and diploid phases of the coccolithophore lifestyle has led, in recent years, to a variety of interesting talks and posters dealing with life cycles and genetics. Jeremy Young and others discussed holococcolith and nannolith biomineralization and Miguel Frada and others discussed the molecular ecology of haplo-dipolid life cycle. It was particularly interesting to note that some haploid stages produced aragonitic morphotypes!

The end of the meeting dealt with talks covering a variety of topics, including impact-damaged calcareous nannofossils at the Silverpit structure (David Jutson and others), oceanographic changes associated with OAE 1d and related extinction events (David Watkins and others) and a look at sediments from the Lower Neogene and Upper Paleogene of ODP Leg 121 (Sharon Stant). A description of the workshops is listed below.

As you can see, I've only touched on a few talks that were presented at INA10. They were all interesting and covered a variety of topics. I rarely have time to deal with Quaternary or younger sediments, or with the genetics of coccolithophores, so for me this meeting was informative and allowed me to think about topics that I don’t usually have time to deal with when I’m at work. I would like to thank Mario Cachao and his associates once again. They put a lot of hard work into this meeting and it showed. The facilities were excellent, the social dinner was delicious (was that method number 99 for preparing Cod??) and I’ve heard from many of the people who participated in the Peddy Paper (I’m not sure I’m spelling that right!) who said they had a blast. To those who dressed up as historical characters and haunted the streets of Lisbon; kudos!! You did a great job and everyone had fun!


1. Emiliania huxleyi Morphological Variation and Biogeography: hosted by Jeremy Young and Jose-Abel Flores.

The conveynors agonized over the patterns of intra-specific variation shown by E. huxleyi. The broad conclusion was that we probably were not fantasizing in subdividing the species into numerous types, but rather may need to recognize more of them. Since E. huxleyi only evolved 250,000 years ago, this makes it one of the most interesting, if still challenging, examples of pseudo-cryptic variation known within the plankton. Topics such as ontogeny, malformation, dissolution, calcification, SEM/LM observations and genetics were discussed. In addition, Jose –Abel Flores discussed the potential for developing a new temperature transfer function for Holocene/Late Quaternary coccoliths and the possibility of holding a workshop on this topic next year.

2. Dissolution Workshop: hosted by Jean M. Self-Trail and David J. Jutson

The conveners presented the group with examples of dissolution of calcareous microfossils, including foraminifera. Examples included dissolution of specimens from cores drilled using oil-based mud, polymer-based mud and water based bentonite and from outcrop samples. Kevin Cooper discussed dissolution of sediments from Angolan deep-water wells. Possible culprits include TOC, sulfuric acid, gypsum, fungal growth and bacteria. Possible mechanical and chemical processes were discussed, including the role that drying has on dissolution, how TOC effects the assemblage, and whether the drilling mud in core samples is causing dissolution. Several possible stop-gap measures that could be used to halt or at least slow down dissolution in both the field and laboratory include freeze drying samples, vacuum packing samples and packing samples in an inert gas such as N2.

Coccolithophores 2003

INA Workshop on extant Coccolithophorid research

October 1-6, 2003, Heraklion/Crete, Greece

Host: Institute of Marine Biology of Crete (IMBC), Dept. of Oceanography Organizer: University of Athens (UOA), Dept. of Geology, Section of Historical Geology-Paleontology

Convener: Maria Triantaphyllou (UOA) Organizing Committee: Jeremy Young (NHM), Patrizia Ziveri (VUA), Michael Dermitzakis (UOA), Tassos Tselepides (IMBC)

At the International Nannoplankton Association meeting (INA 9) in Parma it was recognized that much research is currently in progress on extant coccolithophorids including studies of plankton, sediment trap and core-top samples. It was felt that a special workshop would be useful to facilitate this research, increase collaboration between the different workers, share research results, gain some training, discuss methods and research priorities and identify targets for collaborative research. The University of Athens (UOA) team who has recently started research of coccolithophores in the Aegean Sea area were pleased to have their offer to host this workshop accepted.

The workshop took place at the modern facilities of the Institute of Marine Biology of Crete , near Heraklion on the isle of Crete, Greece, in a friendly and relaxing atmosphere and in the vicinity of the deep-blue Aegean Sea.

During the workshop more than 40 coccolithophorid specialists from several European countries, USA, Australia, Taiwan and Japan tried to catch up with the state-of-the art in coccolithophorid research through frank discussion during one training day plus two and a half days of scientific sessions including 17 talks, 15 poster presentations (with 10 minute introductory talks) and 4 workshop sessions, on the following topics:

Coccolithophorid ecology, Biology, Biogeography. A key presentation by Patrizia Ziveri on distribution of selected species in the Atlantic based on a large database of Holocene sediment samples both revealed patterns which had previously been barely recognized and showed that this type of biogeographic data urgently needs to be re-collected using modern taxonomy. Karl-Heinz Baumann showed that on a large scale there was remarkably high fidelity between the biogeography of coccolithophores in Nordic Seas as observed in the plankton and in the surface sediments.

New lines of ecological research were suggested by research of Maria Triantaphylou on the potential of coccolithophores as pollution indicators using both assemblage reduction and malformation as proxies, with distinctly encouraging preliminary results, and of Markus Geisen on testing of functional hypotheses through measurement and modelling of the mechanical properties of coccospheres.

Several aspects of coccolithophore ecology were addressed, including distribution, composition and seasonal variation in coccolithophore standing crop in various marine environments, including the East China Sea (Tien Nan Yang), Greenland margin, Azores (Joana Barcelos), Portuguese coastline (Aurea Parente, Jorge Ferreira and Mario Cachao), South Adriatic Sea (Barbara Balestra, Maria Marino), Reykjanes Ridge; deep photic zone species (Elisa Malinverno); species-specific coccolith calcite isotopes (Patrizia Ziveri) and a new coccolithophore life-cycle association (Maria Triantaphyllou, Margarita Dimiza and Michael Dermitzakis).

A number of questions related to coccolithophorid ecology, have been addressed: what are the mechanisms that make hetero- turn into holo- stage? what is the holococcolithophore distribution in time and space? what is the role of sibling species in different environments? Several topics needing detailed studies were pointed out: information on detailed coccolithophore biogeography; information related to tropical lagoon environments; accurate knowledge of the middle and deep photic zones; information on the distribution and abundance of naked coccolithophore life-cycle phases.

Coccolithophores and marine carbonate cycles. Sediment trap studies included a three-year series described by Meral Kobrich from off NW Africa with intriguingly strong inter-annual variation. New data were given by Maria Triantaphyllou, Elisa Malinverno, Bianca de Bernardi, Babette Bockel, Harald Andruleit on coccolithophorid export production in the Eastern Mediterranean (Cretan Sea, Ionian Sea) and other parts of the world (Santa Barbara Basin, northwestern Africa, northern Arabian Sea). Patrizia, Markus and Karl-Heinz Baumann discussed calcification, carbon acquisition and estimation of carbonate mass per species.

Harald Andruleit and Jeremy Young highlighted the problem of information loss with only a fraction of the extant biodiversity and assemblage variability being transmitted into the fossil record or even the sediment trap record.

Coccolithophorid Taxonomy. Life-cycle stages and nomenclature problems.

In terms of taxonomy, coccolithophorid research is at a relatively advanced stage, as symbolized by the publication, in time for the meeting, of a new CODENET sponsored Guide to Extant Coccolithophore Taxonomy (Young et al. 2003). However, recent research has highlighted the fact that many conventional species are actually clusters of cryptic or pseudo-cryptic sibling species. New work in this area included documentation of fine scale variation in Florisphaera profunda by Pat Quinn in Coccolithus pelagicus by Aurea Parente, and in the Papposphaeraceae by Lluisa Cros.

Ric Jordan, Lluisa Cros and Jeremy Young introduced a newly revised classification scheme for living haptophytes, stimulating vivid discussion on classification problems of extant and fossil nannoplankton on the light of the newly obtained data on life-cycle associations. Jeremy also gave a thorough and extensive analysis of extant coccolithophorid species richness. Daniela Crudeli demonstrated specific diversity among Pliocene Reticulofenestrids comparable to that seen in the modern nannoflora. Marie-Pierre Aubry discussed the dynamics of extinct nannoplankton and posed several questions, such as estimation of biodiversity and implications for the past, provincialism, and shelf vs. ocean.

Training Sessions -arranged by Ian Probert and Colomban de Vargas (Rutgers University, New Jersey), with assistance from Markus Geisen and Pat Quinn- concerning net collection of living coccolithophores, single cell isolation, microscopic observations of culture strains (thoroughly presented by Ian Probert who gave an extended overview on the biology of haptophytes and stressed the value of exploiting species in culture) and application of molecular genetics to planktonic protists (introduced by Colomban de Vargas) took place. Additionally Betsy Read (California State University San Marcos) analyzed the Expressed Sequenced Tags from Emiliania huxleyi. Finally Sebastian Meier discussed life-cycle studies of oceanic calcareous dinoflagellates. This gave non-biologist coccolithophorid researchers the chance to get acquainted with living forms.

Perhaps the overall conclusion of the meeting was that we now have firm foundations for future research, especially on coccolithophore ecology, as a result of finally having a reasonable understanding of the biology and taxonomy of coccolithophores.

A special issue of Micropaleontology (Micropaleontology Press) of the papers presented at the meeting is being currently edited.

Thanks are due to all the speakers and all those who attended and helped to make it an interesting and scientifically useful meeting.
