OA session at the 2018 annual meeting of the Society for Integrative and Comparative Biology

The Society for Integrative and Comparative Biology (SICB) is hosting its Annual Meeting from January 3-7, 2018 in San Francisco, California. Below find more information on the Ocean Acidification Session taking place Sunday, 7 January, 13:45-15:15. Show More Summary

Decoupling between the response of coral calcifying fluid pH and calcification to ocean acidification

Evaluating the factors responsible for differing species-specific sensitivities to declining seawater pH is central to understanding the mechanisms via which ocean acidification (OA) affects coral calcification. We report here the results...Show More Summary

New study of plankton shells overturns decades-old understanding of their formation and chemistry

The results of new international research into tiny marine plankton will allow scientists to more precisely estimate past ocean conditions and predict future changes, and suggests global warming may have a bigger impact on shell-bearing plankton than previously thought. Show More Summary

Ocean acidification threatens Bering Sea crabs. But can they adapt? (audio)

Ocean acidification could threaten some of Alaska’s most important fisheries. Researchers warn that populations of red king crab in the Bering Sea – made famous by the show The Deadliest Catch – could collapse by the end of the century. But it’s possible the crabs might be able to evolve and adapt to the changing […]

What do jellyfish teach us about climate change?

A new study shows that the biological effects of two ecosystem changes can be greater than their individual impacts What do jellyfish teach us about climate change? A lot. At least that’s what I learned after reading a very recent paper out in the journal Global Climate Change. The article, “Ocean acidification alters zooplankton communities […]

Where Do the Most Narwhals Live?

  Where do you find the most Narwhals on the Earth. Why Narwhals? Well it could be any species. Anglerfish, carnivorous sponge, giraffe, or even a montane unicorn. BUT I WANT TO WRITE ABOUT THE NARWHAL! NOBODY CAN STOP ME! MWAHAHAHA So Narwhals. You probably already know that Narwhals inhabit the Arctic Ocean. But it’s […]

11-2-17 Busy Days for the Lime Kiln Hydrophones

Thursday, November 2nd...October my last post J Pod calls had been on the Lime Kiln hydrophones very, very briefly...that was it......October 31st...they were evidently not seen anywhere......November 1st...they were heardShow More Summary

Effects of the interaction of ocean acidification, solar radiation, and warming on biogenic dimethylated sulfur compounds cycling in the Changjiang River Estuary

Ocean acidification (OA) affects marine primary productivity and community structure, and therefore may influence the biogeochemical cycles of volatile biogenic dimethyl sulfide (DMS) and its precursor dimethylsulfoniopropionate (DMSP) and photochemical oxidation product dimethyl sulfoxide (DMSO).

Carbonate shells change with time

Tiny organisms tell us about climatic condition of the past.   The carbonate shells of tiny marine plankton, foraminifers, are important archives of geochemical records of past climates. Understanding how these plankton make their shells is essential to correctly interpret the geochemical climate signals recorded in them. Show More Summary

Planktic foraminifera form their shells via metastable carbonate phases

The calcium carbonate shells of planktic foraminifera provide our most valuable geochemical archive of ocean surface conditions and climate spanning the last 100 million years, and play an important role in the ocean carbon cycle. These shells are preserved in marine sediments as calcite, the stable polymorph of calcium carbonate. Here, we show that shells […]

Burke-o-Lator helps researchers monitor Sitka’s waters (audio)

For people who depend on the oceans for their livelihood, climate change is about a lot more than weather. Some of the carbon in the atmosphere — which is gradually warming the planet — is absorbed by the oceans, making their basic chemistry more acidic, and making it difficult for organisms like mussels to build […]

4th International Symposium on the Effects of Climate Change on the World’s Oceans

With ICES, PICES, IOC and FAO as primary international sponsors, the 4th International Symposium on the Effects of Climate Change on the World’s Oceans will take place in Washington DC, 4-8 June 2018, and will have many sessions with relevance for the OA community. Show More Summary

New edition of the “OA-ICC Highlights”, July – September 2017

The new edition of the “OA-ICC Highlights” summarizes the project’s main activities and achievements over the period July – September 2017. The information is structured around the OA-ICC three major areas of work: science, capacity building and communication. Show More Summary

The greatest thing ever to happen to science communication

In 133 days from today, the greatest thing ever to happen to science communication will happen in coastal Louisiana. Welcome to OceanDotComm.  Intrigued? You should be. Imagine a conference.  No better yet, imagine a collaborative, storytelling, social media event. Show More Summary

Will Tweeting About Your Research Paper Get You More Citations? Meh.

Currently, one of the most pressing questions in science communication is what impact does participating in these kind of activities have on individual scientists.  These impacts are difficult to quantify as many are indirect, ephemeral,...Show More Summary

Corals’ pH sensor identified

Soluble adenylyl cyclase measures and responds to pH changes in coral cells, but whether it can help the animals withstand ocean acidification is not yet known. Researchers have identified an enzyme that helps corals keep a steady pH in their cells, even as the acidity changes in their environments. Corals experience pH variation due to […]

Identification of a molecular pH sensor in coral

Maintaining stable intracellular pH (pHi) is essential for homeostasis, and requires the ability to both sense pH changes that may result from internal and external sources, and to regulate downstream compensatory pH pathways. Here we identified the cAMP-producing enzyme soluble adenylyl cyclase (sAC) as the first molecular pH sensor in corals. sAC protein was detected […]

Ocean acidification may not affect oyster quality

A team of scientists of the University of Plymouth has found that the eating qualities of UK oysters may not be adversely affected by future ocean acidification and global warming. A study they carried out has shown oysters exposed to levels currently expected to occur over the next century do not lose their sensory qualities, […]

The impact of elevated CO2 on Prochlorococcus and microbial interactions with ‘helper’ bacterium Alteromonas

Prochlorococcus is a globally important marine cyanobacterium that lacks the gene catalase and relies on ‘helper’ bacteria such as Alteromonas to remove reactive oxygen species. Increasing atmospheric CO2 decreases the need for carbon...Show More Summary

Increased temperature mitigates the effects of ocean acidification on the calcification of juvenile Pocillopora damicornis, but at a cost

This study tested the interactive effects of increased seawater temperature and CO2 partial pressure (pCO2) on the photochemistry, bleaching, and early growth of the reef coral Pocillopora damicornis. New recruits were maintained atShow More Summary
