Biologist Duo Suggests Use of Seabirds as Potential Monitors of Ocean Contamination
As per a new study done by a team of biologists (a father-son duo), seabirds are the best options to keep a track on the world oceans increasing chemical contamination. Biologists are of the view that the seabirds can prove to be cheap and effective information gatherers as they make wide-ranging flights over vast stretches of ocean.
The study got published yesterday in journal Science. Co-author Kyle Elliott from University of Manitoba said, "In an afternoon at a seabird colony, for a hundred dollars in gas, you can get information that would cost hundreds of thousands of dollars and lots of time by boat".
Elliott further adds that the seabirds are made-to-order lab assistants as they pick up wide range of traces from wherever they fly. These birds open windows for the happening of the environment as some of them feed over the open ocean, some along the continental shelf and some in close land.
The comparison of older and modern samples taken from these birds can further reveal the changes happening in environment, Elliott added.
The load of contamination and chemicals is increasing in ocean bodies on per day basis which includes banned chemicals as well. People can't imagine which new chemical will emerge as the next persistent global contamination effecting large number of population. Countries like Canada have already accepted seabird as a potential source and did studies, one of them confirming the increasing contamination of mercury.
