Satellite tracking

Follow the migrations of wildlife on the internet
NERI has collected an assemblage of ongoing satellite studies enabling you to follow birds and animals in the landscape. Satellite tracking of animals is a good tool for studying migration routes, areas and behaviour. For the moment NERI has active transmitters on harbour porpoise in Danish marine waters, common eiders at Greenland and narwhales in Baffin Bay.

Pink-footed goose
On 31 March 2004, 7 pink-footed geese equipped with satellite transmitters were released at Vest Stadil Fjord, Western Denmark.
Eiders (Common and King Eider)
In July 2003 researchers from NERI and Canadian Wildlife Service captured 10 King Eiders and 16 Common Eiders in East Bay in North East Canada and equipped the birds with satellite transmitters. In September the NERI researchers were heading for West Greenland, where further 10 King Eiders and 7 Common Eiders were captured at Disko Island and likewise equipped with satellite transmitters.
Narwhales
In August 2003 scientists from NERI, Denmark and Department of Fisheries and Oceans, Canada i Admiralty Inlet has mounted satellite transmitters on 13 narwhales.
Harbour porpoises
When the harbour porpoise is released into the water, it can be followed from the computer home at the office and on the Internet. Through the last 5 years we have followed more than 50 harbour porpoises in the Danish waters.
Mink Whale
5th of june researchers from The Department of Arctic Environment, NERI has mounted a satellite transmitter on the dorsal fin of a mink whale.
Harbour seals and grey seals
We are expecting to catch 10 seals every year until 2005 for satellite transmitter deployment. The results may reveal a change in feeding and breeding areas used by the seals as well as alternative haul-out sites.
Walrus
The aim of this study is to measure the energy expenditure and requirements of individual free-ranging walruses in eastern Greenland. In addition the program will reviel the quantitative importance of predation on the infauna by walruses in Young Sund as well as the relationship between primary production, benthic animals and walruses.
Greenland White-fronted goose
During 1996 - 1999 the migration strategies and staging areas in Iceland and West Greenland of the Greenland White-fronted goose were studied using small satellite transmitters.
Humpback whales
Six humpback whales were equipped with satellite transmitters in June 2000 at the eastern side of Fyllas Banks. The results show, that the humpback whales prefere depth less than 200 m.
The beluga
NERI have together with Greenland Institute of Natural Ressources and Department of Fisheries and Oceans, Canada contributed to the clarification of abundance and stock composition of belugas in the Baffin Bay through arrial surveys and satellite tracking.
Ringed seal
Eight seals were caught and equipped with satellite transmitters in 1996, 5 in 1997 og 10 in 1998. In the open water period daily migration distances were larger than during the fast ice period in winther.
Light-bellied brent geese
Follow satellite-tagged brent geese from Denmark to Svalbard and Greenland.
White-fronted geese
This is a study conducted by the U.S. Fish & Wildlife Service in conjunction with the Institute of Arctic Biology, University of Alaska Fairbanks.
This study has been conducted over two years; 2001 and 2002. In 2001, 12 adult female white fronted geese were outfitted with implanted satellite transmitters, and in 2002, 20 females received transmitters. Separate web pages chart the progress of the cohorts marked in each year.
Black geese
A joint research effort involving the Canadian Wildlife Service (CWS), Washington Dept of Fish & Wildlife (WDFM), U.S. Fish & Wildlife Service (USFWS), U.S. Geological Survey (USGS), and Washington Brant Foundation (WBF).
Ringing
Ringing has shown that Ospreys which breed in Britain spend the winter further south, usually in West Africa. However, little was known about the details of their migration until in 1999 the mystery began to be solved using the latest satellite technology.
Brent geese
Follow the Iceland light-bellied brent geese with satellite transmitters to Canada and back til Ireland on WWT´s homesite. DMU have sponsored a radiotransmitter.
