That feeling when you need lots of blubber to stay warm in the chilly ocean, so your only New Year’s resolution is to nap more.

What did the Boyan Slat and the Ocean Cleanup do last summer?

Because I haven’t written an update on the Ocean Cleanup and Boyan Slat in a while… They deployed a 100-m long prototype that is really 30-year old RO-BOOM technology with some new fancy hardware.   Deployed in only 30 m of water during a calm summer the prototype failed after 2 months. Because shackles. It cost […]

Job opening: Research Oceanographer

The NOAA Pacific Marine Environmental Laboratory (PMEL) Carbon Program is seeking a Research Oceanographer to serve as a research leader for a team of scientists performing research into critical problems on chemical oceanography and related scientific disciplines. Show More Summary

Ocean acidification impacts bacteria–phytoplankton coupling at low-nutrient conditions (update)

The oceans absorb about a quarter of the annually produced anthropogenic atmospheric carbon dioxide (CO2), resulting in a decrease in surface water pH, a process termed ocean acidification (OA). Surprisingly little is known about how...Show More Summary

Tropical CO2 seeps reveal the impact of ocean acidification on coral reef invertebrate recruitment

Highlights CO2 seeps at two coral reefs in Papua New Guinea were used as natural analogues of ocean acidification. Elevated CO2 affected recruitment in marine invertebrate communities. Calcified recruits of reef-dwelling Foraminifera, polychaetes, gastropods, and bivalves were vulnerable to acidification. Show More Summary

The combined effects of reduced pH and elevated temperature on the shell density of two gastropod species measured using micro-CT imaging

The increased absorption of atmospheric CO2 by the ocean affects carbonate chemistry and calcification rates of marine organisms. The impacts of low pH and seawater warming were investigated for the intertidal gastropods Nassarius nitidus and Columbella rustica. Show More Summary

Two Southern Ocean diatoms are more sensitive to ocean acidification and changes in irradiance than the prymnesiophyte Phaeocystis antarctica

To better understand the impact of ocean acidification (OA) and changes in light availability on Southern Ocean phytoplankton physiology, we investigated the effects of pCO2 (380 and 800 µatm) in combination with low and high irradiance (20 or 50 and 200 µmol photons m?2 s?1) on growth, particulate organic carbon (POC) fixation and photophysiology in […]

Seasonal controls of aragonite saturation states in the Gulf of Maine

The Gulf of Maine (GoME) is a shelf region especially vulnerable to ocean acidification (OA) due to natural conditions of low pH and aragonite saturation states (?-Ar). This study is the first to assess the major oceanic processes controlling seasonal variability of the carbonate system and its linkages with pteropod abundance in Wilkinson Basin in […]

nationalaquarium: This week we’re talking pufferfish for our Animal of the Week - like this striped burrfish! Pufferfish inhale water or air to puff up for protection. See more pufferfish here!  The ocean is full of amazing things ^

A turtle’s shell is like a suit of armor, protecting it from predators. While sea turtles can’t draw their arms, legs and heads into their shells, their large size and tough neck skin provide extra protection.  Also helpful: Humans who use our @seafoodwatch app to choose seafood that’s caught in ways that reduce harm to sea turtles! 

1-2-17 The Loss of Granny J-2

Monday, January 1, 2017 When Granny turned 100...I made a birthday card... (that was 5 years ag o) Granny is gone. It breaks my heart. I loved saying (loudly) "there's Granny"...I wanted everyone on the shore to meet Granny, the most famous whale in the wild. Show More Summary

An ocean acidification acclimatised green tide alga is robust to changes of seawater carbon chemistry but vulnerable to light stress

Ulva is the dominant genus in the green tide events and is considered to have efficient CO2 concentrating mechanisms (CCMs). However, little is understood regarding the impacts of ocean acidification on the CCMs of Ulva and the consequences of thalli’s acclimation to ocean acidification in terms of responding to environmental factors. Here, we grew a […]

Seize the day like a black oystercatcher going after prey. These shorebirds are known to sneak up on open mussels, quickly stab their beaks between the shells, sever the muscle, shake the mussel free and swallow it. How’s that for #MondayMotivation?

Happy New Year! The ocean is full of amazing things to appreciate and discover. We’ll be busy working hard to protect the ocean and the creatures that depend on it (including humans!) through education, research and conservation.
