Effects of long-term exposure to ocean acidification conditions on future southern Tanner crab (Chionoecetes bairdi) fisheries management

Demographic models of pre- and post-recruitment population dynamics were developed to account for the effects of ocean acidification on biological parameters that affect southern Tanner crab (Chionoecetes bairdi) larval hatching success and larval and juvenile survival. Show More Summary

L’acidification des océans – Les dessous de l’Océan (in French)

Certains scénarios prévoient une augmentation de 150 % de l’acidité d’ici à 2100. Les écosystèmes marins sont susceptibles d’être affectés par cette acidification accélérée de l’océan et les conséquences risquent d’être lourdes pour la biodiversité dont nous dépendons. Show More Summary

Ocean acidification: the forgotten piece of the carbon puzzle

Ocean acidification – the rise in ocean acidity due to the increased absorption of carbon dioxide (CO?) – is often thought of as consequence of climate change. However, it is actually a separate, albeit very closely-related problem. Ocean acidification is often referred to as “the other CO? problem” because, like climate change, it is primarily […]

New Global Ocean Health report released

Global Ocean Health, a program of the National Fisheries Conservation Center, has recently released a new edition of their “Ocean Acidification Report”. As rightfully asserted by its editing team, the report represents an excellent “timely...Show More Summary

For today’s amazing ocean image, this close-up view of a spiny sand star’s tube feet! These cool creatures have small points, not suckers, on the end of their many tube feet, which allows them to glide over the sea floor with great agility and some speed.

Can art stop pollution?

If you’re a turtle in the ocean, a plastic shopping bag looks a lot like a tasty jellyfish. Did you know, every year on average more than 8 million metric tons of plastic end up in the ocean? In an effort to share the impact single-use...Show More Summary

Porpoising with a purpose

Happy Marine Mammal Monday! Sea lions are famous for their ocean acrobatics, but those behaviors serve a purpose. This one is “porpoising” through the water, a trick that helps sea lions gain speed to hunt or avoid becoming a shark snack. Either way, good luck buddy!

Spectrophotometric measurements of the carbonate ion concentration: aragonite saturation states in the Mediterranean Sea and Atlantic Ocean

Measurements of ocean pH, alkalinity, and carbonate ion concentrations ([CO32–]) during three cruises in the Atlantic Ocean and one in the Mediterranean Sea were used to assess the reliability of the recent spectrophotometric [CO32–] methodology and to determine aragonite saturation states.

Ocean acidification benefits invasive species

The Carcinus maenas, or the European green crab, is one species that doesn’t mind the acidification of the world’s oceans. In fact, this invasive species is thriving here in the U.S. A new study published in Research and Reports in Biodiversity Studies finds that increased carbon levels due to warming water temperatures are benefitting some […]

Effects of high CO2 and warming on a Baltic Sea microzooplankton community

Global warming and ocean acidification are among the most important stressors for aquatic ecosystems in the future. To investigate their direct and indirect effects on a near-natural plankton community, a multiple-stressor approach is needed. Hence, we set up mesocosms in a full-factorial design to study the effects of both warming and high CO2 on a […]

Economic impacts of changes in an Alaska crab fishery from ocean acidification

A dynamic computable general equilibrium (CGE) model is linked to a bioeconomic model for the Bristol Bay red king crab (BBRKC) fishery to analyze regional economic impacts of ocean acidification (OA)-induced changes in fishery yields. Yield projections based on two alternative forms (linear versus nonlinear) of OA effects on the survival of juvenile BBRKC are […]

Biochemical responses to ocean acidification contrast between tropical corals with high and low abundances at volcanic carbon dioxide seeps

At two natural volcanic seeps in Papua New Guinea, the partial pressure of carbon dioxide (pCO2) in the seawater is consistent with projections for 2100. Here, the cover of massive scleractinian corals Porites spp. is twice as high at elevated compared with ambient pCO2, while that of branching corals such as Acropora millepora is greater […]

From the Top Shelf

“I fell in love with seaweed at the kitchen counter. I had returned with a sack full from the windswept beach, and as I dropped each specimen into a tub of saltwater, its form and color and translucent sexuality awakened. Pale pinks mingled with bright greens and yellow oranges. Rounded fronds, bumpy textures, and slender […]

It’s a sleepy #SeaweedSunday!

Blades of giant kelp provide a snug anchor for this sleepy sea otter.  Sea otters like to hang out in kelp forests, where they find their favorite foods and can wrap up in a kelp frond to keep from drifting away at naptime.  Photo by local photographer Jim Capwell.

How to spot a big skate on our Shark Cam

These camouflage experts don’t get as much buzz as their shark and ray cousins, but they’re a beautiful sight! Here’s what to look for:   Shape: Keep your eyes peeled for a flat, fluttering critter that looks like a more angular version of the black bat rays that swoop around our Monterey Bay Habitats exhibit.

The impact of CO2 emissions on ‘nuisance’ marine species (video & text)

Anthropogenic CO2 emissions are being taken up from the atmosphere by the oceans, increasing the availability of dissolved inorganic carbon but reducing both the carbonate saturation and pH of seawater. This ocean acidification affects biological processes in a wide range of marine taxa. Here, we assess the likely responses of ‘nuisance’ species to ocean acidification, […]

Natural variability in the surface ocean carbonate ion concentration (update)
