Goal is to Understand the Ecological Role of Seals in North Atlantic Waters

People come from miles away to see the seals off the shores of Cape Cod and surrounding regions, but the animals are creating some challenges for local fishermen. Recent increases in local seal abundance have led to concerns about fisheries interactions. The urgency of documenting, understanding, and mitigating these interactions has become more apparent.

These and other issues and challenges presented by seal populations have led to the creation of a new effort to improve our understanding of the ecological role of seals in the northeast United States. “This encompasses all issues: how they live, where they go, what they eat, their health and illnesses, and interactions with the world—including us—around them,” says Andrea Bogomolni, a Research Associate at the Woods Hole Oceanographic Institution (WHOI).

Japan fisheries data provides a look at how the ocean is faring 18 months after the worst accidental release of radiation to the ocean in history

Japan’s “triple disaster,” as it has become known, began on March 11, 2011, and remains unprecedented in its scope and complexity. To understand the lingering effects and potential public health implications of that chain of events, scientists are turning to a diverse and widespread sentinel in the world’s ocean: fish.

Events on March 11 began with a magnitude 9.0 earthquake, the fourth largest ever recorded. The earthquake in turn spawned a massive 40-foot tsunami that inundated the northeast Japanese coast and resulted in an estimated 20,000 missing or dead. Finally, the wave caused catastrophic damage to the Fukushima Dai-ichi nuclear power plant, resulting in the largest accidental release of radiation to the ocean in history, 80 percent of which ended up in the Northwest Pacific Ocean.

Deformed Beaks May Signal a Greater Environmental Problem

ANCHORAGE, Alaska – The highest rate of beak abnormalities ever recorded in wild bird populations is being seen in a number of species in the Northwest and Alaska, and scientists to this point have not been able to isolate the cause.

Black-capped Chickadees, Northwestern Crows, and other birds are being impacted by the problem, which affects their ability to feed and clean themselves and could signal a growing environmental health problem.

In birds affected by what scientists have termed “avian keratin disorder,” the keratin layer of the beak becomes overgrown, resulting in noticeably elongated and often crossed beaks, sometimes accompanied by abnormal skin, legs, feet, claws and feathers. Biologists with the U.S. Geological Survey’s Alaska Science Center published their findings in this month’s issue of The Auk, a Quarterly Journal of Ornithology.

“The prevalence of these strange deformities is more than ten times what is normally expected in a wild bird population,” said research biologist Colleen Handel with the USGS, “We have seen effects not only on the birds’ survival rates, but also on their ability to reproduce and raise young. We are particularly concerned because we have not yet been able to determine the cause, despite testing for the most likely culprits.” (more…)
