Friday Smorgasbord: Oyster restoration, testing seabirds and more

By on May 03, 2013

The first May edition of the Friday Smorgasbord has some choice cuts to finish your workweek. First off we have this interesting report about reef restoration — oyster reef restoration that is. Like many of our waterways, the Chesapeake Bay is facing increased nitrogen and phosphorous from fertilizers, wastewater treatment plants and other sources that impairs water quality. However, a new report shows a restored oyster reef can remove up to 10 times more nitrogen from bay than an unrestored area nearby proving reef-restoration can improve water quality in the nation’s largest estuary.

Scientists looking to study how well laws and policies aimed at pollution reduction are working are finding seabirds to be one of the best tools at tracking change. It seems that since seabirds — including pelicans, gulls and terns — are at the top of the food chain they absorb the toxins and pollutants contained in the fish they eat. Because the birds forage over wide areas of oceans but come back to one spot each year to breed, they provide scientists with a one-stop-shop to sample from a broad geographic region. “They essentially go out much of the year onto the ocean, and they sample for you,” said John Elliott, of Environment Canada, who who co-wrote the research with Kyle Elliott of the University of Manitoba. Don’t worry, the birds aren’t killed as toxins can be measured by collecting feathers, blood, oils and small tissue samples.
