Employment record
Associated with the Royal Netherlands Institute for Sea Research (Royal NIOZ) since 1992, first to assess the effects of fisheries on seabirds. Later work focused mainly on natural aspects underlying the distribution of seabirds at sea, which culminated in EC funded projects in which complicated models of foraging decisions of seabirds were parameterised and tested (see below for further details) Formed my consultancy in 1995 (CSR Consultancy), closely associated with Royal NIOZ and IBN-DLO/Alterra (currently Wageningen IMARES) in which applied scientific questions are addressed, such as environmental impact assessments in the North Sea and Wadden Sea for governmental bodies, NGOs and oil companies. Consultancy discontinued in 2006 because of a permanent research position at Royal NIOZ.

Research Interests	Top ^

Apart from a general interest in seabirds and marine mammals (and also in the further trophic levels of the marine food web), my research has mostly had an emphasis on the foraging ecology of marine top-predators and of the interactions between species while at sea. Extensive boat surveys, following standard protocols, in most parts of the North and South Atlantic, including the North Sea, formed the basis of this interest and this has culminated into more detailed studies of the foraging behavior and foraging whereabouts of seabirds and cetaceans at sea. In more recent projects, it is my aim to link reproductive and demographic parameters of breeding seabirds with food availability, prey selection and energetic constraints (foraging range, profitability of feeding, energetic demands of parents and offspring). In these projects, emphasis is on two species of gulls: Larus fuscus and Larus argentatus. Since 1977, the effects of oil pollution on seabirds has been an important topic of study, including impact assessments of major spills, a monitoring programme of oiled beached seabirds in The Netherlands, and necropsies of beached seabirds to evaluate the effects of pollution, but also to study moult, growth, condition, and diet of seabirds at sea.

Projects

Top ^

Commenced studies on seabirds in 1973 with 'Club van Zeetrekwaarnemers' (Netherlands Ornitholgists' Union, NOU), focusing on the visible migration of seabirds and coastal birds along the Dutch coast (1973-82)¹. Currently database manager of the Nederlandse Zeevogelgroep/Club van Zeetrekwaarnemers (holding data of 100,000 hours of observation; records 1.7 million seabirds).

Founded a monitoring programme for stranded oiled seabirds (beached bird surveys) in 1977 ^2,3,4, which became a monitoring tool after 1992 for the Ministry of Transport, Waterways and Public Works (Ministerie van Verkeer en Waterstaat)^5,6 and that set directions for similar research all over Europe ^7,8 (1977-present). Participated in an EC funded project to assess the types of oil and other substances responsible for seabird mortality in The Netherlands, Germany and Denmark (1990-93)⁹. Member of the scientific committee and supervisor of scientific research and impact assessments of the Prestige oil spill (2002/03) in Spain, and responsible for scientific research and impact assessment in the Dutch part of the Tricolor oil spills in 2003. International co-ordinator of the Oiled Guillemot EcoQO (OSPAR, starting in 2007). Scientific studies under the beached bird survey project include studies of morphometrics, age composition, sex ratio and physical condition of wrecked seabirds, the same for birds involved in major oil spills (most recently in a spill in Estonia in 2006 and a spill in The Netherlands in 2007), a skull ossification project with Edward Soldaat (examining ageing characteristics in auks) and a study of post-nuptial moult and chick development in [stranded] Common Guillemots Uria aalge. Ongoing studies of the diet of auks based on stranded specimens.

Studies of the distribution of seabirds at sea (mainly 1985-present) have culminated in the participation in the publication of a number of atlases, books and topical papers ^{29-31,39,45,53,58}. Chairman of the European Seabirds at Sea (ESAS) database group 1997-2007. ESAS database manager for The Netherlands since 1992. Member of advisory committees with regard to fisheries effects (e.g. ICES Working Group on Seabird Ecology), the effects of large infrastructural works at sea and most specifically the potential effects of windfarms at sea in The Netherlands and in Germany (numerous reports, not listed).

Studies on cetaceans commenced in 1982 and have culminated into several publications on the identification and distribution of marine mammals ^{12, 32-38} (1982-present). Recent work is mainly aiming at the integration of studies of important top-predators in marine ecosystems, mainly seabirds and cetaceans ^39-42. A Marine mammal database was established in 1987 and has been maintained as a database manager for the Dutch Seabird group and this database is now the primary and most accessible source of information for the occurrence and relative abundance of cetaceans in the southern North Sea. Personal experience with 42 taxa of cetaceans; personal records: 19,889 individual whales and dolphins (as at March 2007). Author of two field guides, one published in Norwegian, one in Dutch, and several papers on the identification of whales and dolphins. Author of a book on whales and dolphins in the North Sea (2006). Conducted mass autopsies of Harbour Porpoises stranded in The Netherlands in 2006 and 2007 and published the results as a report (NIOZ/IMARES project)see reports under Publications.

Associated with Royal NIOZ since 1992, on a research project on the effect of beamtrawl fisheries on seabirds^17-20. Subsequently co-ordinated two EC funded projects, on behalf of NIOZ studying the effects of discards on seabirds on a North Sea scale (Discards I and Discards II)^21-25. Later work focused mainly on natural aspects underlying the distribution of seabirds at sea^25-27, which culminated in the invitation to join another EC funded project in which a complicated model of foraging decisions of seabirds was parameterised and tested (MIFOS project)^28,47. Initiated and co-ordinated a further EC funded research project (IMPRESS, 2000-2004) evaluating the effects of industrial sandeel fisheries on seabirds. This project was finalised in 2005. The work on fisheries impacts has culminated in several topical papers^{40,43-44,48,50-52,59,} a book^{Cambridge
University Press}, book chapters, and numerous reports; see publications, 2005.

Participated in two and led or guided 12 expeditions into the arctic between 1982 and 2002 (Greenland, Jan Mayen, Greenland Sea, Iceland, Svalbard), which were purely for scientific research (5x) or as tourist guide (9x). Participated in three scientific cruises with TNO-FEL in 2005-2006 in the Bay of Biscay, the Mediterranean, and the Lofoten area as whale expert during sightings surveys with acoustic arrays being operated simultaneously (acoustic trials to identify marine mammals that were logged with high tech acoustic equipment onboard Royal navy vessels Mercuur and Snellius and the Norwegian Forsvarets Forsknings Institut’s vessel Sverdrup II see reports under ‘Publications’.

Operated as tourist guide in the Antarctic in 2007, 2008 and 2009. Studies included seabird population censuses^10-12, seabird migration studies¹³, diet studies^14,15, and systematic surveys for the distribution of seabirds and cetaceans¹⁶. Participated in scientific cruises studying the offshore foraging ecology of seabirds and marine mammals and distribution patterns in relation with oceanographical conditions in the South Atlantic in 2000^46,61 and 2001^56-57 under contract with the Netherlands Institute for Sea Research (RV Pelagia), and to South Georgian waters in 2002 under contract with the British Antarctic Survey (BAS, Cambridge, UK; RV James Clark Ross)⁶³. Contracted for studies on the abundance and distribution of seabirds and marine mammals off Mauritania in 2003 by Woodside Energy Ltd (Australia).

Advisor in Portuguese seabirds at sea project under LIFE (SPEA project NATURA 2000 FRAMEWORK EU’s Policy towards N2000 implementation at Marine areas). Ship-based surveys around the Portuguese mainland (2004-2005) and Madeira (2004). Co-ordinator of the EG Environment Project (2006-2007). Co-organiser of the World Seabird Group Conference, Victoria, 2010.

Most recently, in 2006, I have launched a new project from Royal NIOZ, to evaluate the reproductive success and feeding ecology of Herring Gulls Larus argentatus and Lesser Black-backed Gulls Larus fuscus, including breeding in the Dutch Wadden Sea, to evaluate the effects of prey availability fluctuations, individual levels of specialisation and habitat use, and other factors that might explain the recent failures and population declines in the Herring Gull and the consistently high levels of reproduction and population increase in the Lesser Black-backed Gull. A colour-ring programme was developed and set-up, which is the successor of the Alterra/Arie Spaans colour ringing programme that was transferred from Alterra to Royal NIOZ in 2005. An analysis of the dispersal and annual survival of Herring Gulls ringed between 1986 and 1988 in 14 Dutch colonies is currently under way. Radio telemetry studies in the gull colonies were conducted to evaluate levels of parental care. A large diet study was conducted to evaluate shifts in prey utilised throughout the breeding season and to study individual specialisation. The first papers on these gull studies have meanwhile been published Limosa & Seevögel, see Publications. In 2008 field experiments were conducted to evaluate the possibilities of nest attendance enhancement through supplementary food (RUG masterproject). In a collaboration with University of Amsterdam (Prof W Bouten, D J Shamoun-Baranes), cutting edge technology devices have been deployed in 2008 and 2009, to evaluate foraging distribution patterns of individual birds in great detail.
