From Bivalves To Blue Crabs: Acidification Brings Challenges To New Marine Life

In school, most students learn to measure acidity or pH with a litmus test. Unfortunately, monitoring the acidity of the ocean is not as simple as dunking a small piece of paper in liquid and waiting for the color to change, and the impacts of acidity changes to marine life are more complex than a simple change in color. Atmospheric carbon dioxide is absorbed by the ocean, which makes it difficult for marine calcifiers (a group comprised of many different organisms, such as molluscs, crustaceans, and corals) to make their own shells and skeletons. Ocean acidification doesn’t just harm these creatures. It threatens our nation’s economic stability, from our $7.3 billion seafood industry to our $101.1 billion recreation and tourism sector. But it doesn’t stop there – it also affects our homeland security.

Resiliency Reaches All Corners Of The Coast Thanks To Sea Grant

Students in Alaska take a field trip to a local salmon stream. An artificial reef is built off the coast of Florida. A duck hunter cleans his gear in Wisconsin. A lifeguard in Delaware explains rip currents to a family on their beach vacation. Even though these differing coastal activities take place over the entire continental U.S., they all have the National Sea Grant College Program (Sea Grant), in common. Sea Grant is comprised of a network of 33 programs along the nation’s coasts that support “research, education, outreach, and extension activities that provide communities with the tools to increase their resiliency capacities.” Sea Grant and the Senate Committee on Commerce, Science, and Transportation held a briefing on the necessity of economic resiliency in coastal communities in the U.S. and featured three speakers who attested to the importance of resiliency and of Sea Grant’s support.
