Konstantinos (Kostas) Tsiamis is a biologist, focusing on biological oceanography. He has recently gained his PhD diploma in the Biology Department of Athens University, specializing on macroalgae taxonomy and ecology. Currently, he is a Post-Doc researcher in the Hellenic Centre for Marine Research (HCMR, Greece). Over the past 9 years, he has been studying phycology, focusing on marine macrophytes: seaweeds (green, brown and red macroalgae) and seagrasses. Their biology, ecology, taxonomy and systematics are the main fields of his research. His PhD-thesis focused on alien marine macroalgae off the Greek coasts, with special interest in their taxonomy and impact to the indigenous flora.  In addition, studies of pollution impacts to marine vegetation as well as coastal management are also included in his research topics.

Within the framework of this project in Ascension, his primary research target will be to establish an inventory of Ascension’s seaweed flora. He will be working together with Prof. Frithjof Kuepper. Together, they have done similar phycological exhibitions during the last 3 years in several areas of Greece and Cyprus.

Simon Morley is a marine ecophysiologist at the British Antarctic Survey (BAS) with nearly 20 years experience of physiology research. He has published 40 research papers and book chapters. During this time he has conducted marine surveys and collections in tropical, temperate and polar oceans, gaining a broad knowledge of  fauna in diverse assemblages from deep Antarctic walls to tropical reefs. He has published papers on the physiology of fish, bryozoans and molluscs.

Simon is an experienced dive instructor with over a thousand logged dives on all seven continents and hopes to bring this experience to the team.

Many years ago, Peter started as a blenny expert. During travels all along the coasts of the Mediterranean Sea and West Africa (from Morocco to Cameroon), he detected 10 of the 50 species currently known in that area (plus one from the Cape Verde Islands, which he is currently describing).

Looking around (under water and on land), he noted many other fascinating critters and has now written papers on rather a lot of different species, from protozoans to Homo sapiens.

He spent many years on the Azores and on Madeira Island, travelled frequently to the Cape Verde Islands, and participated in a National Geographic expedition to São Tomé Island. This resulted in numerous papers on the marine fauna and flora and the biogeography of these Atlantic islands

On Ascension, he would particularly like to work on the following groups in co-operation with the experts mentioned:

• Mysid shrimps - Karl Wittmann, Vienna, Austria.


• Brachiopoda - Bernhard Cohen, Great Britain, and Carsten Lüter, Germany.


• Gobiesocidae (Pisces) - Ron Fricke, Stuttgart, Germany.


• Lygdamis (Sabellariidae) - Eijiro Nishi, Japan.


• Zoantharia - James Reimer, Japan.


• Corals - Helmut Zibrowius, France, and Bert Hoeksema, Holland.


• Opisthobranchia - Michael Schroedl, Munich, Germany.


• Eulimidae (Gastropoda) - Anders Warén, Sweden.

For this, he plans to do some night-time snorkeling in large tide pools (when cryptic opisthobranchs emerge) and to dive in caves (if any can be found).

The full list of participants for the marine survey of Ascension Island, August, 2012.

The Shallow Marine Surveys Group is very pleased to present our team of highly qualified and dedicated individuals who will be travelling from around the world to gather in August 2012 on a tiny volcanic island in the middle of the South Atlantic.

We are confident the expedition goals to survey and catalogue the wide diversity of marine life found there will benefit from the collaboration of such a diverse international team bringing a wide range of backgrounds and experience to the effort.

In the weeks to come we will be introducing the individuals involved with more detail on their backgrounds and personal objectives for the expedition. We will also invite team members to post their own thoughts and experiences as they take part in the expedition.
