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

Seagrass meadows off Spain. (Photo: Oceana / Sergio Gosálvez) - New research shows that seagrass has an incredible ability to spread over vast distances of the ocean, which gives them an ability to migrate with climate change and be able to recover from habitat disturbance. Show More Summary

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 […]

Meet the Eerie Stargazer, Wolf-Fish, and Polka Dot Batfish: The Halloween Creature Feature Edition

Wolf-fish. (Photo: Gaellery / Flickr Creative Commons) If you’re an ocean lover, you’re probably familiar with some of the ocean’s creepiest monsters of the deep—like anglerfish, with their glowing lures to trick their prey, to the blob sculpin, a ghostly-looking creature that’s sure to give anyone a fright.

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. […]

Benthic coral reef calcium carbonate dissolution in an acidifying ocean

Changes in CaCO3 dissolution due to ocean acidification are potentially more important than changes in calcification to the future accretion and survival of coral reef ecosystems. As most CaCO3 in coral reefs is stored in old permeable sediments, increasing sediment dissolution due to ocean acidification will result in reef loss even if calcification remains unchanged. […]

The potential of ocean acidification on suppressing larval development in the Pacific oyster Crassostrea gigas and blood cockle Arca inflata Reeve

We evaluated the effect of pH on larval development in larval Pacific oyster (Crassostrea gigas) and blood cockle ( Arca inflata Reeve). The larvae were reared at pH 8.2 (control), 7.9, 7.6, or 7.3 beginning 30 min or 24 h post fertilization. Exposure to lower pH during early embryonic development inhibited larval shell formation in […]

Multiple driving factors explain spatial and temporal variability in coral calcification rates on the Bermuda platform

Experimental studies have shown that coral calcification rates are dependent on light, nutrients, food availability, temperature, and seawater aragonite saturation (? arag), but the relative importance of each parameter in natural settings remains uncertain. Show More Summary
