Master thesis title:

Seasonal dynamics of sympagic meiofauna communities in a high Arctic fjord, Van Mijenfjorden, Svalbard.

Master thesis project description:

Sea ice is a vital component of the Arctic ecosystem, organisms of all size classes dependent on it as a habitat, feeding, breeding and nursery ground. Microscopic organisms that inhabit the brine channels in the interior of the ice are known as sympagic (ice-associated) meiofauna (> 20 μm). Allochthonous (not indigenous) sympagic meiofauna originate from the pelagic and benthic realm and inhabit first-year ice to feed and fuel growth and development, as well as take refuge from predators.

This project is part of FAABulous (Future Arctic Algal Blooms – and their role in the context of climate change) and it aims at identifying what pelagic and benthic species utilize seasonal landfast ice each year as a breeding and nursery ground, in Van Mijenfjorden. An experimental part of the thesis investigates the growth rates and feeding ecology of the dominant sympagic meiofauna in Van Mijenfjorden; nematodes and polychaete larvae.

Start date: March 2017
Planned submission date: May 2019

International, national and institutional involvement:

I have been a member of GLOBEC (Global Ocean Ecosystem dynamics) Focus 1 Working Group on retrospective analysis and time series studies and I was involved in the GLOBEC-SPACC initiative (Small Pelagics and Climate Change).

I have been a member and chair of several expert groups at the International Council for the Exploration of the Sea (ICES). I am currently co-chairing the Working Group on International Deep Pelagic Surveys (WIDEEPS) and member of the Arctic Fisheries Working Group (AFWG).

I have been a member of the Sir Alister Hardy Foundation for Ocean Science (SAHFOS, UK) board of directors (2001-2005) and a member of the council as sponsoring governor of the foundation on behalf of fremer (2006-2007).

I have participated in the EU-projects TASC, SAP, UNCOVER, RECLAIM and DEEPFISHMAN.

I have been part of the Marine Ecology Progress Series board of review editors (1998-2005) and was associate editor for Fisheries Oceanography (2007-2010). I have refereed more than 250 manuscripts and proposals.
