Cleopatra II - The Team

Here we present the team involved in the CLEOPATRA II project.


Janne E. Søreide (Project leader, This email address is being protected from spambots. You need JavaScript enabled to view it.)

Completed her Dr. scient (equal to PhD) at the University of Tromsø in 2007. Her main scientific focus is on Arctic marine organisms’ timing of key life cycle events and potential to adapt to a rapid changing Arctic. Her research rely on high resolution field studies throughout the year, including the polar night, combined with advanced laboratory measurements and experiments to determine key Arctic invertebrates’ nutritional, metabolic and reproductive status under different environmental conditions and seasons.  Currently she is an associated professor at the University Centre in Svalbard.

Øystein Varpe (leader of the modelling unit)

Øystein is an ecologist particularly interested in evolutionary and seasonal ecology. His main scientific focus is on how seasonality shapes ecological processes and evolutionary adaptations, topics particularly relevant in the high-latitude ecosystems of the Arctic. Central topics in Øystein's work include zooplankton life-history strategies, phenology and behavior. In the Cleopatra II project Øystein contributes to the empirical studies and leads the work package on life history modelling. More about Øystein's work at:

Maciej Ejsmond (post doc modelling)

Jørgen Berge 

Completed his PhD at the University of Tromsø in 2000. His main scientific focus centres on two topics; ecosystem responses to climate change and the biological processed during the polar night. Currently he is a professor at the University of Tromsø and an adjunct professor at UNIS (Svalbard).

Malin Daase

Malin completed her PhD in Marine Biology at the University of Bergen in 2008. Her research interest are in Arctic marine ecology with particular interest in zooplankton and sea ice biota ecology, population dynamics and life history adaptations of copepods and effects of variation in the physical environment on zooplankton distribution and life history traits. For the last 4 years she has been a researcher at the Norwegian Polar Institute and collaborated in CLEOPATRA II experiments and field campaigns. From March 2014 she will be employed at the University in Tromsø as a post doc within Marine Night and CLEOPATRA II.

Eva Leu

Completed her PhD in Marine Biology at the University of Oslo in 2006. Postdoc at the Norwegian Polar Institute (CLEOPATRA), and UNIS. Researcher position at Alfred-Wegener-Institute for Polar and Marine Research. Her main fields of research are algal ecophysiology and physical-biological coupling of climate change effects on Arctic marine systems. In the CLEOPATRA projects she studied the impact of seasonal changes on the nutritional quality and physiology of sea ice algae and phytoplankton, and their consequences for grazers. Currently she is employed as a researcher at Akvaplan-niva.

Haakon Hop

Haakon is a senior research scientist in marine biology at the Norwegian Polar Institute, leader of ICE-ecosystems and in charge of scientific diving. His research interests are: Ecology and bioenergetics of pelagic, sympagic (ice-associated) and hard-bottom invertebrates and fishes in Arctic marine environments. Marine ecosystem structure (stable isotopes), energy flow (lipids), and bioaccumulation of persistent pollutants in Arctic marine food webs. Integration of physical and biological data in multidisciplinary research projects carried out in the Marginal Ice Zone (MIZ) and fjords in Svalbard.

Martin Graeve

Dr. Habil. Ksenia Kosobokova

Completed her PhD at Shirshov Institute of Oceanology, Russian Academy of Sciences in 1981, and completed her Habilitation at the same institute in 2010. Her main scientific focus is on the Arctic marine zooplankton, including zooplankton taxonomy, biodiversity, life cycles strategies, reproductive biology and ecology. She has conducted her studies in all Russian Arctic seas (Kara, Laptev, East-Siberian, Chukchi and the White seas) and in the central Arctic Ocean. Currently she is a Leading Researcher at Shirshov Institute of Oceanology Russian Academy of Sciences (Moscow, Russia).

Daniela Freese (PhD candidate)

Daniela doing her PhD at the Alfred Wegener Institute in Bremerhaven, with a strong cooperation with UNIS, Svalbard.Hermain research interest aims at theecology and physiologyof zooplankton in a changing Arctic, with a focuson the winter metabolism of Arctic zooplankton.

Eike Stübner (PhD candidate)

Eike  finished her master in marine benthic biogeography in 2007 (UiT, UNIS). She is working on meroplankton seasonality and timing using high resolution time series and feeding experiments. Her general interest is in marine ecosystem dynamics.

Miriam Marquardt (PhD candidate) 

Miriam did finish her Master in the field of Polar Ecology at the University of Kiel (Germany). In the scope of her PhD studies, she is investigating all kinds of protists  (10 – 0.45 um) in the waters around Svalbard with use of molecular approaches (MicroFun project). She is trying to determine the diversity of the microbial food web during the polar night. Further she is looking into temporal and spatial changes in the microbial community structure throughout the year, and how these protists are influenced by their environment.

Maja Hatlebakk (master student)
Lauris Boissonnot (master student – finished June 2013)
Katarzyna Blachowiak-Samolyk
Kasia Dmoch
Rafał Boehnke
Anette Wold

Charlotte de Vries

Lotte is doing her masters in Limnology and Oceanography at the University of Amsterdam. During her research project at UNIS, she will try to estimate Calanus glacialis mortality rates using the data gathered in Billefjorden as part of the Cleopatra project.

Daniel Vogedes

Daniel is employed by UiT The Arctic University of Norway as a technician by the Marine Night project and by UNIS for CLEOPATRA II for which he joins as field assistant, maintains equipment and is responsible for data collection and web page administration. He has also a commercial divers licence and Norwegian motorboat certificate. He recently finished his PhD at UNIS/UiT on the role of Calanus in the Arctic marine ecosystem. In addition to his job in Marine Night and CLEOPATRA, he holds at temporary 20% position as field technician in the biology department at UNIS.
