Biophysical feedbacks mediate carbonate chemistry in coastal ecosystems across spatiotemporal gradients

Ocean acidification (OA) projections are primarily based on open ocean environments, despite the ecological importance of coastal systems in which carbonate dynamics are fundamentally different. Using temperate tide pools as a natural...Show More Summary

Boron isotopes as a proxy for pH in siliceous and calcareous marine algae

Rising CO2 in the atmosphere has directly led to a reduction in surface ocean pH -a process known as ocean acidi?cation. There is a need to understand past climates in terms of ocean pH change in order to be able to relate these to the current e?ects of climate change on marine organisms. One way […]

Effects of bicarbonate on cardiac function in fish

An entirely novel mechanism to modulate heart rate was recently discovered in the Pacific hagfish (Eptatretus stoutii): a soluble adenylyl cyclase (sAC)-mediated pathway that increases cyclic adenosine monophosphate (cAMP) production upon stimulation by HCO?? to increase heart rate.

CO2-induced ocean acidification impairs the immune function of the Pacific oyster against Vibrio splendidus challenge: an integrated study from a cellular and proteomic perspective

Highlights • Combined effects of elevated pCO2 and Vibrio splendidus challenge on the Pacific oyster are investigated. • Vibrio infection aggravates the oyster immunosuppressive effect caused by ocean acidification. • Vibrio infection aggravates the oyster immunosuppressive effect caused by ocean acidification.

Interaction between elevated CO2 and phytoplankton-derived organic matter under solar radiation on bacterial metabolism from coastal waters

Microcosm experiments to assess bacterioplankton response to phytoplankton-derived organic matter obtained under current and future-ocean CO2 levels were performed. Surface seawater enriched with inorganic nutrients was bubbled for 8 days with air (current CO2 scenario) or with a 1000?ppm CO2–air mixture (future CO2 scenario) under solar radiation.

5 more years of progress in Washington state

Some of my favorite early summer evenings were spent on the Puget Sound with the Olympic Mountains in view and the salty smell of the ocean nearby. My friends and I would get together at the local marina to grab beers and a bag of oysters from the dockside shop. Then at the picnic tables […]

The neurobiology of climate change

Directional climate change (global warming) is causing rapid alterations in animals’ environments. Because the nervous system is at the forefront of animals’ interactions with the environment, the neurobiological implications of climate change are central to understanding how individuals, and ultimately populations, will respond to global warming.

Climate change is altering lakes and streams, study suggests

To scientists who study lakes and rivers, it seems humans have embarked on a huge unplanned experiment. By burning fossil fuels, we have already raised the concentration of carbon dioxide in the atmosphere by 40 percent, and we’re on track to increase it by much more. Some of that gas may mix into the world’s […]

Ocean acidity: trouble for shellfish (video)

http://www.wabi.tv/templates/2015_Sub_Video_Share?contentObj=468772663 In today’s Science with Dr. Bob experiment we are talking about ocean acidification and what that means for shellfish. Last time Dr. Bob was here we talked about greenhouse gas emissions and the abundance of CO2 being added to the atmosphere. Show More Summary

A hard shell: how mussels are affected by ocean acidification

Research carried out on day-old mussel larvae explores the effect of a changing climate on shell development, with potential applications for aquaculture and biotechnology. Scientists studying calcium in a marine environment have discovered a direct link between the acidification of the seas in a changing climate and the rate at which mussels develop their calcified […]

Climate change drives collapse in marine food webs

A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine “food webs”. Published in the open access journal PLOS Biology, the study’s lead author PhD student, Hadayet […]

Climate change could drive marine food web collapse through altered trophic flows and cyanobacterial proliferation

Global warming and ocean acidification are forecast to exert significant impacts on marine ecosystems worldwide. However, most of these projections are based on ecological proxies or experiments on single species or simplified food webs. How energy fluxes are likely to change in marine food webs in response to future climates remains unclear, hampering forecasts of […]

The bill “Coordinated Ocean Monitoring and Research Act” has passed Senate

Bill Passed: A bill to reauthorize the Integrated Coastal and Ocean Observation System Act of 2009, and for other purposes. The bill passed the Senate Jan 08, 2018. It was originally sponsored by (R) Senator Roger Wicker from MS. Summary: Coordinated Ocean Monitoring and Research Act This bill revises and reauthorizes through FY2021 the […]

Internship opportunity: “Analysis of ocean acidification and co-stressor effects on fish early life processes,” National Center for Coastal Ocean Science, New Jersey, USA

This project evaluates the potential effects of ocean acidification and other environmental co-stressors on fish populations. The effects on fish of an increased level of ocean acidification –another consequence of C02 emissions – are largely unknown and represent a new and exciting research front. We are using a combination of field, laboratory, and experimental data […]

Diatom performance in a future ocean: interactions between nitrogen limitation, temperature, and CO2-induced seawater acidification

Phytoplankton cells living in the surface waters of oceans are experiencing alterations in environmental conditions associated with global change. Given their importance in global primary productivity, it is of considerable concern to...Show More Summary

Taking the metabolic pulse of the world’s coral reefs

Worldwide, coral reef ecosystems are experiencing increasing pressure from a variety of anthropogenic perturbations including ocean warming and acidification, increased sedimentation, eutrophication, and overfishing, which could shift reefs to a condition of net calcium carbonate (CaCO3) dissolution and erosion.
