Uncovering Shrimp Seafood Fraud: Diaries from the Field, Part One

(Photo: Rachel Golden) Yesterday, Oceana released a new report that uncovered widespread misrepresentation of America’s favorite seafood: shrimp. The report found 30 percent of DNA-tested shrimp samples to be misrepresented—often mislabeled for another species or said to be wild caught when it was farmed—across more than 100 restaurants and grocery stores nationwide. read more

Physiological response of Crocosphaera watsonii to enhanced and fluctuating carbon dioxide conditions

We investigated the effects of elevated pCO2 on cultures of the unicellular N2-fixing cyanobacterium Crocosphaera watsonii WH8501. Using CO2-enriched air, cultures grown in batch mode under high light intensity were exposed to initial...Show More Summary

Skeletal mineralogy of geniculate corallines: providing context for climate change and ocean acidification research

Marine species depositing high-magnesium (Mg) calcite (>8% MgCO3) are projected to be among the first to show response to the impacts of climate change, i.e. increased sea surface temperature (SST) and ocean acidification (OA), given the increasing solubility of calcite in seawater with increasing Mg content. Temperature is a major driver of Mg incorporation into […]

How much weight is the “Ocean Atlas” really carrying on its shoulders?

Artist Jason deCaires Taylor has teamed up with B.R.E.E.F. to create “Ocean Atlas”, the worlds largest underwater sculpture. Underwater reef, diverter of tourists from natural reefs and a new hub for underwater selfies, “Ocean Atlas” is a sculpture of a woman supposedly holding the weight of the ocean on her shoulders.

These are a few of my favorite species: almost zombie like brachiopods

The lowly brachiopod.  They make my list because they represent the antithesis of a charismatic organism. Today the attention they get is mostly by mistake. Brachiopods are often confused for mollusks because of their superficial resemblance to clams. But if it wasn’t for that pesky Permian mass extinction, they might be kicking clam butt all over the place. 99% […]

CEO NOTE: Chilean Oil Spill Harms Local Wildlife, Fishing Communities

Oiled seawater near the Monobuoy Terminal in Chile. (Photo: Oceana / Claudio Almarza) Nearly a month ago I heard some troublesome news from my Oceana colleagues in Chile: A sizeable oil spill had occurred in Quintero Bay, harming local marine life and jeopardizing the local fishing communities. read more

Ocean Roundup: Seagrass Travels via Ocean Currents, Plump Leatherbacks Can Swim More Easily, and More

Graphics: New Oceana Study Finds Shrimp Misrepresented in the U.S.

(Photo: Oceana) Today, Oceana released a new study that found shrimp, America’s favorite seafood, to be misrepresented in the United States. In the only known study of its kind in the U.S., DNA testing confirmed that 30 percent of 143 tested shrimp products—found in 111 restaurants and grocery stores—were misrepresented. read more

Climate experts say ocean acidification is hurting the Belize Barrier Reef

The Belize Barrier Reef is the longest in the Western Hemisphere, and the second-longest in the world. It is also on the frontlines of climate change, with new observed impacts arising from increase ocean acidity. BELMOPAN, Belize, October 27, 2014 (AMG) — The effects of climate change are weighing heavily on the fishing and tourism […]

Effects of ocean acidification on development of Alaskan crab larvae

The oceans absorb a large proportion of the carbon dioxide gas (CO2) emitted into the atmosphere. This CO2 changes the chemistry of seawater to make it more acidic, a phenomenon termed ocean acidification. Ocean acidification can have negative impacts on marine fauna, especially during early life stages, presenting a risk to ecosystems and fisheries. This […]

Ocean acidification in the aftermath of the Marinoan glaciation

Boron isotope patterns preserved in cap carbonates deposited in the aftermath of the younger Cryogenian (Marinoan, ca. 635 Ma) glaciation confirm a temporary ocean acidification event on the continental margin of the southern Congo craton, Namibia. Show More Summary

Comparative responses of two dominant Antarctic phytoplankton taxa to interactions between ocean acidification, warming, irradiance, and iron availability

We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a clustered matrix of three global change variables (CO2,...Show More Summary

Deep-water boost for a community exposed to ocean change: Mesocosm experiment on the effects of ocean acidification at its summit

29. October, 2014/ Kiel, Taliarte. In a long-term field study led by GEOMAR Helmholtz Centre for Ocean Research Kiel, an international team of scientists investigates the effects of ocean acidification on pelagic ecosystems in the subtropical Atlantic. The field experiment with the KOSMOS mesocosms off Gran Canary now culminates in the simulation of deep-water upwelling […]

Spatio-temporal variability of polychaete colonization at volcanic CO2 vents indicates high tolerance to ocean acidification

Ocean acidification is predicted to have negative effects on marine biota, resulting in the loss of biodiversity and changes in marine ecosystem structure and function. However, some species and life stages may be capable of thriving in low pH conditions, either due to their natural ability to tolerate stressful low pH–high pCO2 conditions and/or alteration […]

Interview with the Vampire Blennies

This is our second guest post from ichthyologist, tech diver and all-round good guy Dr. Luiz Rocha at the California Academy of Sciences.  You should follow him on Twitter When you hear “vampires” you usually think “Twilight”, “Vampire Diaries” or “True Blood”. However, a very interesting group of fishes have also taken up the name. […]
