After months of travel across the Pacific, journalists Craig Welch and Steve Ringman unveiled the thorough and striking series of videos, photographs and interviews that underline just what ocean acidification will mean for people. Welch and Ringman capture a changing ocean, focusing on how increasing acidification will impact communities along the Pacific Rim including American crab and shellfish industries.
The iconic oyster industries on both the East and West coasts have been coping with the effects of ocean acidification for almost a decade now—and research is showing that crabs and other shell-forming species may be seeing direct impacts soon.
The species in the crosshairs are not only culturally relevant, but also economically valuable—supporting jobs and feeding millions. This is serious business for the United States and other nations that depend on a healthy ocean.

More than 70 species of shark occur in the Gulf of Mexico and along the U.S. Atlantic coast. Of those, we catch over a dozen large and small coastal species during the bottom longline population survey I’m participating in with the National Oceanic and Atmospheric Administration.
Here are five of the species we commonly spot:
Atlantic Sharpnose Shark This small shark is the most commonly caught species during our survey because it is ubiquitous in this region. In the right depths, it is not uncommon for us to catch around 50 of these small sharks per set of 100 hooks.
Population status: Due to their abundance in the western North Atlantic, their population status is not considered to be of great concern. Apart from humans, Atlantic sharpnose sharks also have other, larger sharks to fear as predators.

While most people out on the water are trying to avoid sharks, I’m on a boat that’s looking for them. We’re trying to find out which shark species are doing well and which ones are in trouble.
The answer: it’s complicated. But one important piece of evidence is the information collected on scientific surveys of population abundance, like the one I’m on right now.
It’s my third year as a volunteer on the science crew with the National Oceanic and Atmospheric Administration. I am currently on the NOAA ship OREGON II, a 170-foot research vessel with its home port in Pascagoula, Miss.
This is the first leg of the annual shark and red snapper bottom longline survey. The survey is conducted in the U.S. Gulf of Mexico from South Texas to the Florida Keys and along the East Coast up to Cape Hatteras, N.C. That’s a total of four legs lasting two weeks each.
2013 may be a very windy year. All along the Atlantic Coast, offshore renewable power has been getting a boost. In states from North Carolina to Maine, growing support for wind energy has led to practical steps that will get this industry moving.
Like many of you, many of Ocean Conservancy’s staff have lived through hurricanes and other natural disasters. We know how much damage hurricanes can cause, and our hearts go out to those of you affected by Hurricane Sandy.
Hurricane Sandy, which pounded the East Coast on Monday, was a wholly different storm. Our immediate concerns are always with those in the path of such devastating storms, especially those on the New Jersey coast and New York where the damage was especially acute. We send our gratitude to NOAA for the warnings and the time to prepare and to the first responders, who are not only saving lives but are leading communities’ recovery efforts.
As we shift from rescue to recovery, we are confronting a cleanup and rebuilding effort with an extraordinary price tag and an unforeseeable timeline. And while we can’t control such a massive storm, we can help strengthen our nation’s best defense against this force of nature.
Imagine if the United States could lay claim over vast stretches of pristine open ocean and coral reefs in the Pacific Ocean. What if we could expand our nation’s control over the marine environments in the Arctic, the Gulf of Alaska and the Bering Sea? And how might it benefit our country if we could extend our existing maritime borders along the East Coast, West Coast and the Gulf of Mexico?
It would be like a giant ocean Louisiana Purchase. Except this time, the United States wouldn’t have to pay a dime.
Expansion of U.S. borders may seem like the stuff of history books. But what I’m talking about here isn’t history. And it isn’t fantasy. It’s a very real choice facing the U.S. Senate right at this very moment.
