Defense responses to short-term hypoxia and seawater acidification in the thick shell mussel Mytilus coruscus

The rising anthropogenic atmospheric CO2 results in the reduction of seawater pH, namely ocean acidification (OA). In East China Sea, the largest coastal hypoxic zone was observed in the world. This region is also strongly impacted by...Show More Summary

Calculating surface ocean pCO2 from biogeochemical Argo floats equipped with pH: an uncertainty analysis

More than 74 biogeochemical profiling floats that measure water column pH, oxygen, nitrate, fluorescence, and backscattering at 10-day intervals have been deployed throughout the Southern Ocean. Calculating the surface ocean partialShow More Summary

Timing of global regression and microbial bloom linked with the Permian-Triassic boundary mass extinction: implications for driving mechanisms

New high-resolution U-Pb dates indicate a duration of 89?±?38?kyr for the Permian hiatus and of 14?±?57?kyr for the overlying Triassic microbial limestone in shallow water settings of the Nanpanjiang Basin, South China. The age and duration of the hiatus coincides with the Permian-Triassic boundary (PTB) and the extinction interval in the Meishan Global Stratotype Section […]

Ocean acidification buffering effects of seagrass in Tampa Bay

The Intergovernmental Panel on Climate Change has identified ocean acidification as a critical threat to marine and estuarine species in ocean and coastal ecosystems around the world. However, seagrasses are projected to benefit from...Show More Summary

The social cost of carbon

The social cost of carbon (SCC) provides a monetary measure of the net global harm resulting from a small increase in atmospheric carbon dioxide. Conversely, it also measures the net reduction in harm (social benefit) from a decrease. Federal agencies in the United States have developed a range of estimates of the SCC, with core […]

Invitation to participate in the online Ocean Acidification Forum, 9-30 March 2017

Dear Colleagues, I would like to extend an invitation to participate in a moderated online discussion forum on Ocean Acidification to support the global stakeholder input process toward the convening of the UN SDG 14 Ocean Conference in June later this year in New York. The Conference is being co-hosted by the Governments of Sweden […]

Sunday, March 12th...a couple days ago, my attention was drawn to many gulls that were skimming the surface of the water...they were going after bait fish - that's a sign of Spring......so the next morning I thought I would go look for...Show More Summary

Look at These Amazing Deep-Sea Creatures from the Remote Pacific Right Now

Pterygophora is ptery-fic! Also known as northern sea palm, Pterygophora californica is an important member of the kelp forest community. With a woody stipe equipped to handle surging seas, fields of Pterygophora create a forest-within-the-kelp-forest—all the more real estate for fishes and invertebrates to thrive. Happy Seaweed Sunday!

How to recover when something goes very, very wrong at sea

No shit, Sherlock. A staggering achievement – fishing for a 2m thing in 5000m water with a 10,000m line … very, very well done. https://t.co/gvKiU23H9B — Sheldon Bacon (@sheldonbacon) March 10, 2017 I could not have said it better myself. Last weekend the wire cable that the ship’s CTD hangs from snapped, sending the entire […]

The geologic history of seawater pH

Although pH is a fundamental property of Earth’s oceans, critical to our understanding of seawater biogeochemistry, its long-timescale geologic history is poorly constrained. We constrain seawater pH through time by accounting for the cycles of the major components of seawater. We infer an increase from early Archean pH values between ~6.5 and 7.0 and Phanerozoic […]

White-spotted anemones are delicate but deadly—they use their sticky tentacles to snare passing fish! You can find these stunners in our Monterey Bay Habitats gallery.

Friday, March 10th 3:30 a.m. - yes the middle of the night... J Pod came back in......they were vocalizing and echolocating for over 2 hours on the Lime Kiln hydrophones......I heard them a bit on Orca Sound as well, but they seemedShow More Summary

A comparison of MgCO3 in individual sub-components of major skeletal structures of the common temperate sea urchin Paracentrotus lividus

The major skeletal structures (test, spines, Aristotle’s lantern) of a common regular sea urchin Paracentrotus lividus were analyzed for Mg-calcite composition to determine their relative vulnerability to ocean acidification. Percentage...Show More Summary

Primary utricle structure of six Halimeda species and potential relevance for ocean acidification tolerance

Variations in utricle morphology may be responsible for different tolerances to ocean acidification (OA) within the macroalgal genus Halimeda, an important sediment producer on reefs. However, differences in species’ utricle morphology and their relationship to calcification and crystal formation have not been well articulated. Show More Summary

Contrasting microbial community changes during mass extinctions at the Middle/Late Permian and Permian/Triassic boundaries

Microbial communities are known to expand as a result of environmental deterioration during mass extinctions, but differences in microbial community changes between extinction events and their underlying causes have received little study to date. Show More Summary
