Future ocean in a chamber

Australian scientists will create a ‘future ocean’ under the sea ice off Casey this summer, using four underwater chambers to measure the impact of ocean acidification on seafloor (‘benthic’) communities. (…) The four semi-enclosed chambers will be deployed on the seafloor, 10 to 20 m beneath the Antarctic sea ice off Casey station, between November […]

Capps introduces bill to combat ocean acidification

Rep. Lois Capps (CA-24) introduced the Ocean Acidification Research Partnership Act, legislation that will support research on ocean acidification through partnerships between the seafood industry and the academic community. Ocean acidification occurs when carbon dioxide dissolves in seawater, leading to the water becoming more acidic. Show More Summary

Seagrass biofilm communities at a naturally CO2-rich vent

Seagrass meadows are a crucial component of tropical marine reef ecosystems. Seagrass plants are colonized by a multitude of epiphytic organisms that contribute to broadening the ecological role of seagrasses. To better understand how...Show More Summary

Farewell My Friends

“When one man, for whatever reason, has the opportunity to lead an extraordinary life, he has no right to keep it to himself.”  -Jacques Yves Cousteau I can think of no two men this quote applies to more than Rick Macpherson and Al Dove.  For the last five years, these two men have shared freely […]

Ocean acidification in the Global Calculator

The Global Calculator is a model of the world’s energy, land and food systems that allows users to explore the options for reducing global emissions to 2050, and to see the climate consequences of these choices to 2100. It is a free, interactive and open-source tool that helps you to understand the link between our lifestyle, the […]

Malacology Monday

You already know that Deep Sea News provides expert reporting, in-depth analysis, first-person research, and sarcastic mockery of contemporary topics relevant to our ocean world. Unlike other popular science sites that can be wildly imaginative and dangerously inaccurate, DSN’s crew of scientists cut through the pop-science b.s. Show More Summary

Why the Foldscope is My New Favorite Toy

This past year Eric Betzig, Stefan Hell, and William Moerner received the Nobel Prize in Chemistry “for the development of super-resolved fluorescence microscopy.” From simply putting two pieces of glass together for magnification purposes to being able to follow individual molecules within a cell, I think saying we have come far in the field of […]

Hawaiian Monk Seal meets Manta Rays from Manta Ray Advocates Hawaii. “Waimanu – a Hawaiian Monk seal – was seen at the Manta Ray Night Dive a few times over the past few weeks, but always on the dark outskirts. Last … Continue readi...

What’s this viral video mystery blob? (hint: it’s not a pyrosome)

Hi lovely internet. I’ve noticed lots of folks getting really excited about a new video going viral. Many are calling this giant strange worm a pyrosome. Now, I love pyrosomes. I’ve written about pyrosomes and am very honored that news sites are quoting my article in their coverage of this video. Thank you. It means a lot and […]

Atmospheric Carbon Dioxide

Since 1750, the atmospheric concentration of carbon dioxide has increased by about 32% (from about 280 to 376 parts per million in 2003), primarily due to the combustion of fossil fuels and land use changes. Approximately 60% of that increase (60 parts per million) has taken place since 1959.         Data: Millennium […]

Carbonate chemistry in the northern South China Sea shelf-sea in June 2010

The distributions of dissolved inorganic carbon (CT), total alkalinity (AT) and pH at 25 °C (pH25) were determined in the northern South China Sea Shelf-sea (NoSoCS) in early June, 2010 during a low flow period. The distributions of the partial pressure of CO2 (pCO2), in situ pH, and temperature normalized pCO2 (NpCO2) were derived from the […]

The effects of water acidification, temperature and salinity on the regenerative capacity of the polychaete Diopatra neapolitana

Changes in seawater pH, temperature and salinity are expected to occur in the near future, which can be a threat to aquatic systems, mainly for marine coastal areas, and their inhabiting species. Hence, the present study proposes to evaluate the effects of temperature shifts, pH decrease and salinity changes in the tissue’s regenerative capacity of […]

The carbonate mineralogy and distribution of habitat-forming deep-sea corals in the southwest pacific region

Habitat-forming deep-sea scleractinian and alcyonacean corals from around the southwest Pacific were analysed for their calcium carbonate mineralogy. Scleractinian coral species Solenosmilia variabilis, Enallopsammia rostrata, Goniocorella...Show More Summary

Physiological responses and scope for growth upon medium-term exposure to the combined effects of ocean acidification and temperature in a subtidal scavenger Nassarius conoidalis

Physiological responses (ingestion rate, absorption rate and efficiency, respiration, rate, excretion rate) and scope for growth of a subtidal scavenging gastropod Nassarius conoidalis under the combined effects of ocean acidification (pCO2 levels: 380, 950, 1250 ?atm) and temperature (15, 30°C) were investigated for 31 days.

Are the ocean and atmosphere finally cooperating and is El Niño really here? Probably.

El Niño has been playing with my heart for a whole year now. It’s coming. It’s not coming. It’s gonna be huge. It’s not coming now. The ocean looks like en EL Niño but the atmosphere doesn’t. Y U SO FICKLE THE CHILD? I cut my loses, ran from this atmospheric/ocean phenomena prediction and healed my bruised […]

Ocean acidification along the Gulf Coast and East Coast of the USA

As part of an effort to monitor changes in inorganic carbon chemistry of the coastal ocean, near-synoptic cruises are being conducted in the Northern Gulf of Mexico and along the East Coast of the United States. Here we describe observations obtained on a cruise in the summer of 2012 and compare them with results from […]
