A monthly round-up of news and trends important to the AltaSea community.
Exxon Misled the Public on Climate Change, Study Says (New York Times)
As Exxon Mobil responded to news reports in 2015 that said that the company had spread doubt about the risks of climate change despite its own extensive research in the field, it urged the public to “read the documents” for themselves.
Now two Harvard researchers have done just that, reviewing nearly 200 documents representing Exxon’s research and its public statements and concluding that the company “misled the public” about climate change even as its own scientists were recognizing greenhouse gas emissions as a risk to the planet.
As ocean waters warm and acidify, corals across the globe are disappearing. Desperate to prevent the demise of these vital ecosystems, researchers have developed ways to “garden” corals, buying the oceans some much-needed time. University of Miami Rosenstiel School marine biologist Diego Lirman sat down with Josh Chamot of Nexus Media to describe the process and explain what’s at stake.
Giant Plankton May Help Move Plastic Pollution to Sea Floor (The Scientist)
Plastic pollution has emerged as a real threat to Earth’s ecosystems, especially in the ocean. But microscopic bits of plastic that swirl near the surface may have a route to deeper layers. Giant larvaceans, members of the marine zooplankton that swim in the upper layers of ocean waters worldwide, may be capable of ingesting microplastic pollution and transporting it to deeper parts of the sea, according to researchers at the Monterey Bay Aquarium Research Institute (MBARI).
On its 50th anniversary, the landmark theory of island biogeography–the study of the distribution of species on islands over time–expands from land to sea with fascinating results. A team of researchers led by Dr. Hudson Pinheiro, postdoctoral ichthyologist at the California Academy of Sciences, have proposed a new conceptual model of island biogeography for marine organisms–a theory that explores how different processes (like sea level fluctuations and geographic isolation) influence marine species diversity around islands. The team found that, despite some similarities, the forces that tend to shape diversification and community assemblage on land are different from those that impact islands’ marine environments.
SUSTAINABLE AND INNOVATIVE BUSINESS
Federal officials declared Pacific bluefin tuna are not on the verge of becoming extinct, but local harbors are still pursuing opportunities to ramp up seafood production in Southern California.
At least two port agencies have been actively pursuing opportunities in aquaculture, with the Port of San Diego recently revealing details about four pilot projects and the Ventura Port District aiming to develop production of shellfish in the Santa Barbara Channel.
Ecosystems are under pressure all over the world, and monitoring their health is crucial. But scientific monitoring is very expensive, requiring a great deal of expertise, sophisticated instruments and detailed analysis, often in specialized laboratories. Research suggests that social media platforms such as Twitter and Instagram could be a rich source of free information for scientists tasked with monitoring the health of coral reefs and other environmental assets.
The majority of the world’s aquaculture is concentrated in only a few countries – most notably, China, Indonesia, and India. Most of this production takes place either on land or in coastal habitat, where environmental impacts are often severe. Evidence shows that innovative offshore technologies can dramatically reduce the environmental impact of large-scale commercial fish farming. UCLA IoES research builds off a previous study sponsored by the Science for Nature and People Partnership (SNAPP) that identified regions around the world with high biological potential for offshore farming of fish and bivalves.
The project focuses on six countries: Morocco, Oman, Palau, Philippines, United Arab Emirates and the United States of America, and, identified areas of high ecological potential which can possibly introduce or improve the current aquaculture situation. The researchers partnered with The Nature Conservancy (TNC), and are working directly with Science for Nature and People Partnership (SNAPP) and National Center for Ecological Analysis and Synthesis (NCEAS) to produce a report that shows how aquaculture may be a strong candidate for marine conservation programs.
There’s an estimated 51 trillion pieces of plastic in the ocean, most of it broken up into bits smaller than the nail on your pinkie finger. Marine animals eat this plastic when they mistake it for fish eggs, plankton and algae. And so do people when they slurp down oysters, consume crab or eat other types of fish and shellfish, according to the latest research on the presence of plastic in fisheries and aquaculture issued by the United Nations Food and Agriculture Organization.
