Kathryn Sullivan

We recently told you about Dr. Kathryn Sullivan, the astronaut-turned-ocean champion who was just confirmed as the head of the National Oceanic and Atmospheric Administration (NOAA). NOAA aims to provide “science, service and stewardship” to the American people. It works to understand and predict changes in weather, climate, the ocean and coasts, and to conserve and manage marine ecosystems and resources.

If being the first American woman to walk in space isn’t impressive enough for you, she’s also earned her chops as an ocean explorer.

After working as an astronaut for the National Aeronautics and Space Administration, she served as an oceanographer in the U.S. Navy Reserve for 18 years, and became chief scientist for NOAA in 1993. She has also served as NOAA’s assistant secretary of commerce for environmental observation and prediction and deputy administrator. Sullivan’s roles have given her experience in a variety of topics, including fisheries biology, climate change and marine biodiversity.

With such a lifelong passion for the ocean, we’re happy to see her leading NOAA. She has proven that she cares about protecting the ocean and the people who depend on it. After being approved as head of NOAA, Sullivan said, “NOAA provides the environmental intelligence that helps citizens, businesses and governments make smart choices. Mission first, people always—this is my commitment to the American people and to the NOAA workforce.”

Sue Moore

Dr. Sue Moore is a NOAA biological oceanographer who studies the ecology, bioacoustics and natural history of whales and dolphins living in the Arctic. She currently serves on a variety of boards and committees for which she uses her scientific expertise to protect marine mammals from the effects of man-made sounds, whaling and other threats.

Moore has served on the U.S. delegation to the International Whaling Commission to push for the use of scientific data in the protection and management of vulnerable whale species. She’s also worked with the National Marine Mammal Laboratory and as an associate professor at the University of Washington.

Recently, some of her research has used acoustic sonobuoys and hydrophones (tools for recording underwater noises made by whales) to determine the number and distribution of whales, seals and other animals in the Arctic while seeing if sounds could be linked to behavioral patterns. As we continue to see changes in the Arctic, marine mammals are canaries in the coal mine. Scientists can gather insight into physical changes in their ecosystem through their behavior and response.

“Marine mammals can act as ecosystem sentinels because they respond to climate change through shifts in distribution, timing of their movements and feeding locations,” Moore said. “These long-lived mammals also reflect changes to the ecosystem in their shifts in diet, body condition and physical health.”

Sarah Cooley

Dr. Sarah Cooley is an earth scientist who currently works as the science outreach manager for Ocean Conservancy’s Ocean Acidification program. She recently joined us from Woods Hole Oceanographic Institution in Massachusetts where she researched communities affected by ocean acidification.

At Ocean Conservancy, Cooley continues to work with oceanographers, fishery scientists, economists, geographers and policy specialists to collect data on how quickly ocean acidification is occurring, how it affects marine species, how humans use those species and the potential it has to impact society and the economy.

Cooley has already begun a number of projects, including attending the 2014 Ocean Sciences Meeting in Honolulu. She’s also active in the social media sphere, sharing her thoughts on all things related to ocean acidification.

Regarding her passion for developing solutions to ocean acidification, Cooley said, “My hunger for exploring people’s experiences of global change has now lured me into the policy world. I’m excited to distill technical knowledge into lessons that real people can use to plan ahead.”

Arctic Sea Ice Reaches Record Low http://blog.oceanconservancy.org/2012/08/28/arctic-sea-ice-reaches-record-low/ http://blog.oceanconservancy.org/2012/08/28/arctic-sea-ice-reaches-record-low/#comments Tue, 28 Aug 2012 13:35:25 +0000 Carmen Yeung http://blog.oceanconservancy.org/?p=2540

This visualization shows the extent of Arctic sea ice on Aug. 26, 2012, the day the sea ice dipped to its smallest extent ever recorded in more than three decades of satellite measurements. The line on the image shows the average minimum extent from the period covering 1979-2010, as measured by satellites. Every summer the Arctic ice cap melts down to what scientists call its “minimum” before colder weather builds the ice cover back up. The size of this minimum remains in a long-term decline.

The National Snow and Ice Data Center has just announced critical ice in the Arctic Ocean melted to record low levels this summer. The Washington Post reports:

“As of Sunday, the Arctic sea ice cover had shrunk to 1.58 million square miles, the smallest area since satellite measurement began in 1979. With the melting season not yet over, the ice will almost certainly contract further in the coming weeks before it begins to re-form.”

Arctic sea ice plays an important role in moderating the global climate. The bright surface of sea ice reflects sunlight back into space. Each year, portions of it melt in the summer, exposing the ocean surface. While the sea ice can reflect about 50 to 70 percent of the sunlight back into space, the dark ocean absorbs approximately 90 percent of the sunlight, heating the water and causing Arctic temperatures to rise even further. This process creates a feedback loop as warmer temperatures cause further sea ice melt. The reduction in Arctic sea ice has far reaching impacts on global atmospheric patterns and ocean circulation. Learn more about the important role sea ice plays in regulating the global climate here.

Here at Ocean Conservancy, we have been urging the government to stop Shell’s Arctic drilling plans and protect this fragile and vitally important region. A green light for Arctic drilling would mean placing an already stressed environment in greater jeopardy, which isn’t worth the risk. The decrease in seasonal sea ice has created the potential for a dramatic expansion of oil and gas exploration in Arctic waters. Currently, there is no adequate technology, technique or infrastructure to respond effectively to an oil spill in icy Arctic waters, and darkness, hazardous weather, or sea conditions could delay spill response for weeks.

Even without a major accident, day-to-day oil and gas operations create significant environmental disturbances. Seismic testing, exploratory drilling, and increased vessel and air traffic associated with oil and gas operations generate noise and air and water pollution, with the potential to affect whales and other marine animals and, in turn, the people who depend on them for subsistence.
