Hi ???? I wanted to ask you something. Sea lions often approach divers and people they find swimming where they are. As people must keep a certain distance and not go and approach some animals (whales and dolphins, for example) unless the animal decides

It’s a great question! Watching marine mammals in their natural habitat can be a great way to learn about the environment and promote conservation (plus, it’s fun!). But it’s always important to give animals lots of space to live their lives and carry out their daily activities. Show More Summary

The role of biological rates in the simulated warming effect on oceanic CO2 uptakel

Marine biology plays an important role in the ocean carbon cycle. However, the effect of warming-induced changes in biological rates on oceanic CO2 uptake has been largely overlooked. We use an Earth system model of intermediate complexity to investigate the effect of temperature-induced changes in biological rates on oceanic uptake of atmospheric CO2 and compare it with […]

Calcite dissolution kinetics at the sediment-water interface in natural seawater

The absorption, or uptake, of anthropogenic CO2 by the oceans results in a decrease in pH and carbonate ion concentration, [CO32 ?]; as a consequence, the saturation state of seawater with respect to CaCO3 minerals (calcite, aragonite) falls, leading to a shallowing of their saturation depths and triggering an increase in their dissolution at the seafloor. Nearly one-third […]

Pride, Actually.

It’s June, and that means the end of the NBA, the start of summer, and the celebration of LGBT Pride across the USA.  I must admit that Pride crept up on me this year.  I’ve recently returned from a long stretch of field work in Africa (another post soon on the toughest field work of […]

Octopus suckers are the swiss army knives of ocean survival! Features include an iron grip, as well as the ability to taste and smell. Indispensable for an octopus on the prowl. ????????

Physiological responses of gray mullet Mugil cephalus to low-pH water

We examined changes in the physiological responses of gray mullet Mugil cephalus exposed to acidic seawater (pH 6.0, 6.5, 7.0) and normal seawater (pH 8.0, control) for 15 days. As pH decreased, survival rate and body weight also decreased. Show More Summary

Release of Version 5 of the Surface Ocean CO2 Atlas – celebrating 10 years of SOCAT!

On behalf of the Surface Ocean CO2 Atlas (SOCAT) scientific community, we are proud to announce the release of SOCAT Version 5! SOCAT is a synthesis activity by the international marine carbon research community (>100 contributors).Show More Summary

Scales and drivers of seasonal pCO2 dynamics and net ecosystem exchange along the coastal waters of southeastern Arabian Sea

The impact of seasonal coastal upwelling on the dynamics of dissolved inorganic carbon (DIC) and sea-air fluxes of CO2 along the coastal waters of Kochi was investigated during 2015, as a part of Ecosystem Modelling Project. The surface water pCO2 varied from 396 to 630 ?atm during the study period. Significant inter-seasonal variations were found in the distribution of […]

Combined effects of elevated pCO2 and warming facilitate Cyanophage infections

Elevated pCO2 and warming are generally expected to influence cyanobacterial growth, and may promote the formation of blooms. Yet, both climate change factors may also influence cyanobacterial mortality by favoring pathogens, such as viruses, which will depend on the ability of the host to adapt. Show More Summary

Combined effects of sea water acidification and copper exposure on the symbiont-bearing foraminifer Amphistegina gibbosa

Coral reefs are threatened by global and local stressors such as ocean acidification and trace metal contamination. Reliable early warning monitoring tools are needed to assess and monitor coral reef health. Symbiont-bearing foraminifers...Show More Summary

6-17-17 Transients and Residents Today

Saturday, June 17th - the transients......here is a short clip of what they did during that encounter.........while watching the transients we learn of Residents, L Pod, on the west side and they were coming down island...we headed that way......more on that encounter later...

noaasanctuaries: Summer is a great time to enjoy all things strawberry — including strawberry anemones! At Cordell Bank National Marine Sanctuary, these inch-wide anemones carpet the sea floor. They use their tentacles to capture food and to defend themselves. As plentiful as they are, we doubt they’d taste great in a strawberry shortcake. (Photo: NOAA)

montereybayaquarium: Um, seriously? One of our pharaoh cuttlefish got that feeling you get when you’re trying to have a serious conversation, but everyone is distracted by the guy playing with his food.

Herrera, Kilmer team up on ocean acidification issue

WASHINGTON, D.C. — Two U.S. representatives from Washington state, Derek Kilmer and Jaime Herrera Beutler, have reintroduced bipartisan legislation to help fight ocean acidification. The bill, entitled the Ocean Acidification Innovation Act (H.R. Show More Summary

Acid–base physiology, neurobiology and behaviour in relation to CO2-induced ocean acidification

Experimental exposure to ocean and freshwater acidification affects the behaviour of multiple aquatic organisms in laboratory tests. One proposed cause involves an imbalance in plasma chloride and bicarbonate ion concentrations as aShow More Summary

The rise of CO2 and ocean acidification

Ocean acidification is a closely linked consequence of increasing carbon dioxide (CO2) in the atmosphere, involving multiple changes in seawater chemistry. Observed long-term trends are superimposed on natural variability over a range of space and time scales. Show More Summary

Genome-wide transcriptional reprogramming in the seagrass Cymodocea nodosa under experimental ocean acidification

Here we report the first use of massive scale RNA-Sequencing to explore seagrass response to CO2-driven ocean acidification (OA). Large-scale gene expression changes in the seagrass Cymodocea nodosa occurred at CO2 levels projected by the end of the century. C. Show More Summary
