Last month, a collection of maps representing one of the largest known efforts to assemble and disseminate spatial data for multiple species of marine life was released in New England. This powerful new information database characterizes over 150 marine species through map based visualizations.
These data enhance our fundamental understanding of marine species and where they exist in the ocean, bringing us a step closer to a more comprehensive assessment of marine resources. In the end, the goal is to better inform decision-makers who are tasked with improving ocean ecosystems and enhancing our ocean economy.
We love polar bears! And, when we saw that today was International Polar Bear Day—we jumped for joy. While you sit here reading this fascinating blog, polar bear moms are busy caring for their newborn cubs in their Arctic dens.
If you didn’t love these Arctic bears enough already, we’re giving you six more reasons to love them. Join us in celebrating polar bears today!
We know that not everyone has the time to peruse hundreds of pages of information, so Ocean Conservancy and the National Wildlife Federation partnered to summarize what we now know about impacts. This summary is based on five years of government research, which recently became available when the details of the BP settlement were released last month.
November is the month for cozy sweaters and cold weather. Sadly, manatees don’t have the luxury of going out and buying warmer clothes to prepare for winter weather. Beginning in November, many manatees make their way from the cooling Mid-Atlantic coast to the warm waters around Florida. That is why November has the honor of being Manatee Awareness Month!
This month got off to a great start with Polar Bear Week, we just didn’t think November could get any better — but it did — with Manatee Awareness Month! To celebrate our favorite sea cow, here are a few reasons why we love these gentle, easy going marine mammals.

Nearly two weeks after a ruptured pipeline spilled 105,000 gallons of crude oil near Santa Barbara, hundreds of tired and oil-soaked workers are still on site working to scoop, boom and skim what they can of the 21,500 gallons estimated to have reached the ocean. As the slick spreads on the surface, and more oil sinks beneath the waves, a complicated environmental, chemical and biological process is unfolding in the waters of the Santa Barbara Channel. While every oil spill differs depending on local conditions, science and past history allow us to anticipate some of the long-term impacts to marine wildlife, habitats and communities.
Oil produced offshore of Santa Barbara is particularly heavy and thick, likely worsening the effects of external exposure to marine birds, mammals and fish. These effects include smothering those animals that can’t move, and impairing the ability of some animals to insulate against cold water. Marine birds that become oiled may lose the ability to fly, forage and feed their young. Highly mobile birds and marine mammals that frequent the ocean surface, where spilled oil initially collects, are especially vulnerable. They may be exposed to oil in one location only to sicken or die elsewhere. The spill’s location in shallow, nearshore waters exposes a particularly rich array of wildlife and habitats to damage, including shorelines, sea grass, kelp beds, rocky reefs and kelp forests.
Yesterday, scientists from the National Oceanic and Atmospheric Administration (NOAA) published new results from a series of studies in which they have investigated the unusually high number of dolphin deaths occurring in the Gulf of Mexico. Since 2010, scientists have conducted autopsies on dead dolphins to try and understand why they are dying.
They found significantly higher numbers of dolphins with severe lung disease and lesions on their adrenal glands in oiled areas than in non-oiled areas. Dr. Stephanie Venn-Watson described the adrenal disease as forcing dolphins to precariously balance on a ledge which cold temperatures, pregnancy and infection can push them off, resulting in death. The lesions observed in dolphins were “some of the most severe lung lesions ever seen in wild dolphins throughout the U.S.” according to lead Pathologist, Dr. Katie Colegrove. NOAA is decisive in concluding that the BP Deepwater Horizon oil disaster caused the dolphin deaths in the Northern Gulf: “The timing, location, and nature of the detected lesions support that contaminants from the Deepwater Horizon oil spill caused these lesions and contributed to the high numbers of dolphin deaths within this oil spill’s footprint.”
Earlier this year, President Obama took executive action to protect some of the Arctic Ocean’s most significant marine areas from the threats posed by oil and gas drilling. Unfortunately, some areas of the Arctic Ocean were left open to oil companies, and oil giant Shell has been gearing up to make another attempt to drill in the Chukchi Sea this summer.
The National Oceanic and Atmospheric Administration (NOAA) recently released an analysis that details how Shell’s proposed drilling operations may impact whales and seals. The results? Tens of thousands of of animals may be exposed to noise that could disrupt vital life activities like migration, breathing, nursing, breeding, feeding, and sheltering. NOAA’s analysis determined that more than 50,000 seals and more than 6,000 whales–including belugas, bowheads, grays, and humpbacks–could be affected by Shell’s proposed drilling activities.
