“Why should men have all the fun?” The seafaring ladies of physical oceanography
There are definitely a lot of research cruise videos out there. But this one caught my eye because, HEY, it focuses on physical oceanography! You learn about the Agulhas current, expensive st is thrown into the ocean and you get to meet a bunch of female physical oceanographers! It’s a little long but definitely worth... Show More Summary
Oceana CEO Andy Sharpless Discusses His New Book, The Perfect Protein
Nine billion of us are estimated to be on the planet by 2050, and the demand for food will increase by 70 percent above today’s levels. If land and fresh water are already under strain, how in the world are we going to feed a population...Show More Summary
Physiological compensation for environmental acidification is limited in the deep-sea urchin Strongylocentrotus fragilis
Anthropogenic CO2 is now reaching depths over 1000 m in the Eastern Pacific, overlapping the Oxygen Minimum Zone (OMZ). Deep-sea animals – particularly, calcifiers – are suspected to be especially sensitive to environmental acidification associated with global climate change. Show More Summary
CO2-driven ocean acidification reduces larval feeding efficiency and change food selectivity in the mollusk Concholepas concholepas
We present experimental data obtained from an experiment with newly hatched veliger larvae of the gastropod Concholepas concholepas exposed to three pCO2 levels. Egg capsules were collected from two locations in northern and central Chile, and then incubated throughout their entire intra-capsular life cycle at three nominal pCO2 levels, ?400, 700 and 1000 ppm (i.e. […]
Tidal downwelling and implications for the carbon biogeochemistry of cold-water corals in relation to future ocean acidification and warming
Cold-water coral (CWC) reefs are recognised as ecologically and biologically significant areas that generate habitats and diversity. The interaction between hydrodynamics and CWCs has been well-studied at the Mingulay Reef Complex, a relatively shallow area of reefs found on the continental shelf off Scotland, UK.

Multiple physiological responses to multiple environmental challenges: an individual approach
The injection of anthropogenically-produced CO2 into the atmosphere will lead to an increase in temperature and a decrease in pH at the surface of the oceans by 2100. Marine intertidal organisms possess the ability to cope in the short term with environmental fluctuations exceeding predicted values. However, how they will cope with chronic exposure to […]
Effects of ocean warming and acidification on survival, growth and skeletal development in the early benthic juvenile sea urchin (Heliocidaris erythrogramma)
Co-occurring ocean warming, acidification and reduced carbonate mineral saturation have significant impacts on marine biota, especially calcifying organisms. The effects of these stressors on development and calcification in newly metamorphosed juveniles (ca. Show More Summary
The effect of ocean acidification on early algal colonization stages at natural CO2 vents
Marine algae exhibit different responses to ocean acidification, suggesting that a decrease in pH does not always favour marine photosynthetic organisms. In order to understand the effect of acidification on algal community development,...Show More Summary
Arctic rhodolith beds and their environmental controls (Spitsbergen, Norway)
Coralline algae (Corallinales, Rhodophyta) that form rhodoliths are important ecosystem engineers and carbonate producers in many polar coastal habitats. This study deals with rhodolith communities from Floskjeret (78°18?N), Krossfjorden (79°08?N), and Mosselbukta (79°53?N), off Spitsbergen Island, Svalbard Archipelago, Norway. Show More Summary
Occurrence of a cold-water coral along natural pH gradients (Patagonia, Chile)
Increasing dissolution of anthropogenic-released carbon dioxide into the world’s oceans is causing ocean acidification (OA). OA is thought to negatively affect most marine-calcifying organisms, notably cold-water corals (CWC), which may be especially sensitive due to the deep and cold waters they normally thrive in. However, the impact of OA on CWC is difficult to predict. […]
Results of laboratory and field experiments of the direct effect of increasing CO2 on net primary production of macroalgal species in brackish-water ecosystems
Studies on the effects of increasing acidification on marine communities have been previously mostly carried out in truly marine areas whereas brackish-water ecosystems such as the Baltic Sea have been less studied. The current study...Show More Summary
The central carbon and energy metabolism of marine diatoms
Diatoms are heterokont algae derived from a secondary symbiotic event in which a eukaryotic host cell acquired an eukaryotic red alga as plastid. The multiple endosymbiosis and horizontal gene transfer processes provide diatoms unusual opportunities for gene mixing to establish distinctive biosynthetic pathways and metabolic control structures.

The Worst Thing I Ever Saw Underwater (and Why it Matters This Week)
On Friday, August 3rd, 2007, I landed the Deepworker submersible at 1,052 feet in the second largest underwater canyon in the world, Pribilof Canyon in Alaska’s Bering Sea. In the distance, I saw the lights of the other submersible, piloted by Michelle Ridgway. As we both sat on the bottom conducting life support checks and [...]
Polar waters: the challenges of accelerated acidification
Dr Donna Roberts, an Australian scientist from the University of Tasmania, is head of the FOCE Antarctic project. In partnership with the Monterey Bay Aquarium Research Institute (MBARI) in California, she wants to evaluate the effects of the acidification of polar waters on marine organisms. A real challenge since the drop in pH, which is […]

Stanford scientists develop underwater labs to study coral and climate change
Picture a tropical paradise and you might conjure something like Heron Island, Australia. Two hours by catamaran from the town of Gladstone, Queensland, the sandy island’s 40 acres are shared by a resort, a scientific research station, and thousands of black noddies, a dusky and talkative seabird that nests in the lime-green pisonia trees each […]
Coastal states may reap federal funds
With the world’s oceans and coasts facing growing challenges from sea-level rise, ocean acidification and increasing temperatures, the U.S. Senate took action last week to protect America’s vital ocean resources. The Senate voted 68-31 to approve an amendment offered by U.S. Show More Summary
Ocean acidification in Washington State: an exploration of its chemical, biological, and societal impacts
Saturday 15 June 2013, 4 PM Part of the Seattle Science Festival Ocean acidification is caused by very well understood chemical processes, though its progression in coastal estuaries is complicated by a variety of human activities. The US Pacific Northwest is a hot spot for rapid progression of ocean acidification. The region’s oyster industry has […]
