noaasanctuaries: A mother and calf humpback whale glide through the surface waters in Hawaiian Islands Humpback Whale National Marine Sanctuary.  After a nearly 12-month gestation period, a female humpback whale gives birth to a single calf that she closely nurtures and feeds for six to 10 more months.

Chemical composition of two mineralogically contrasting Arctic bivalves’ shells and their relationships to environmental variables

The main goal of this study was to determine the concentrations of trace elements in the mineralogically contrasting shells of two Arctic bivalves: Chlamys islandica and Ciliatocardium ciliatum. Aragonite shells seem to be more susceptible to the binding of metal ions, which is most likely a result of their crystal lattice structure. We suggest that […]

Export of calcium carbonate corrosive waters from the East Siberian Sea

The Siberian Shelf Seas are areas of extensive biogeochemical transformation of organic matter, both of marine and terrestrial origin. This in combination with brine production from sea ice formation results in a cold bottom water of relative high salinity and partial pressure of carbon dioxide (pCO2). Data from the SWERUS-C3 expedition compiled on the icebreaker […]

Resilience to ocean acidification: decreased carbonic anhydrase activity in sea anemones under high pCO2 conditions

Non-calcifying photosynthetic anthozoans have emerged as a group that may thrive under high carbon dioxide partial pressure ( pCO2) conditions via increased productivity. However, the physiological mechanisms underlying this potential success are unclear. Show More Summary

From smooth to bumpy, how Marie Tharp changed our view of the sea floor

Give a woman some data, and she’ll change the science world. At least that’s what Marie Tharp did. A skilled cartographer, her maps showed the bottom of the ocean was not just a vast boring underwater plain, but contained bumps, ridges, mountains and trenches. And you know Marie’s really kickass when her findings incited Jacques Cousteau to […]

The seasonal cycle of carbonate system processes in Ryder Bay, West Antarctic Peninsula

The carbon cycle in seasonally sea-ice covered waters remains poorly understood due to both a lack of observational data and the complexity of the system. Here we present three consecutive seasonal cycles of upper ocean dissolved inorganic carbon (DIC) and total alkalinity measurements from Ryder Bay on the West Antarctic Peninsula. We attribute the observed […]

Contrasting effects of ocean acidification on coral reef “animal forests” versus seaweed “kelp forests”

Ocean acidification is the sustained absorption of anthropogenically derived CO2 and is a major threat to marine ecosystems. Ocean acidification results in the decline of seawater pH (increase in protons) and carbonate ions and increased CO2. Added CO2 could benefit terrestrial forests, but changes in the concentration of any one of aspect of the carbonate […]

This copepod blue our mind! Sea sapphires are tiny crustaceans that are invisible one moment, and brilliant blue the next, thanks to fancy scales that reflect incoming light. This little gem is currently in our Drifters Gallery! Check out this cool video from @deepseanews of sea sapphires in action: (photo: staffer Travis Johnson)

We think there’s no animal too bizarre to exhibit beautifully. In fact, the heartless, brainless and spineless brown sea nettles are Aquarium icons, and are by far our most photographed animals. Who’s got a jelly photo to share? Photo of a photo by guest Jeff Reynolds

kqedscience: Watch the Snail-Smashing, Fish-Spearing, Eye-Popping Mantis Shrimp The killer punch of the mantis shrimp is the fastest strike in the animal kingdom, a skill that goes hand in hand with its extraordinary eyesight. They can see an invisible level of reality using polarized light, which could lead to a breakthrough in detecting cancer. Show More Summary

Young king crabs found hitchhiking on sea pigs

Young king crabs found hitchhiking on sea pigs: How do juvenile king crabs avoid predators on the open seafloor? Research from scientists at Monterey Bay Aquarium Research Institute (MBARI) and Monterey Bay National Marine Sanctuary indicates they get by with a little help from wandering sea cucumbers (aka sea pigs)!

The butterflies are here! Every year, thousands of monarch butterflies flutter their way to California’s Central Coast for the winter.  Check out the Pacific Grove Museum of Natural History to follow this year’s migration count, find out where to view the butterflies and learn how you can help monarchs 

Acidification poses threat to sea life (edited)

A Call to Action from a member of a West Coast alliance in the United States of America says what climate change is doing to oceans; together with ocean acidification, it may have direct consequences if left unchecked. Mr Jay Manning sounded the warning at a side event during the ongoing 22nd Conference of the […]

Acidification of Coral reefs: proposal

TRACC is developing proposals (partners wanted) to create solutions to the acidification of coral reefs by climate change. We will take what is known from reef resilience to pH change and experimental coral planting methods around the world and to proactively prepare the groundwork for adaption strategies to identify and grow coral species capable of […]

Translating crustacean biological responses from CO2 bubbling experiments into population-level predictions

Many studies of animal responses to ocean acidification focus on uniformly conditioned age cohorts that lack complexities typically found in wild populations. These studies have become the primary data source for predicting higher level...Show More Summary

Calcareous nannofossils at the Triassic/Jurassic boundary: stratigraphic and paleoceanographic characterization

In this work, calcareous nannofossils are identified for the first time in the uppermost Triassic sequence of the Lombardy Basin (Southern Calcareous Alps, Italy). Two zones are recognized, namely the NT2b (latest Triassic) and the NJT1 (earliest Jurassic). Show More Summary

Biomineralization and global change: A new perspective for understanding the end-Permian extinction

We investigated the kill mechanisms of the end-Permian mass extinction by analyzing patterns in biomineralization of marine invertebrates. The microstructures of Upper Permian brachiopod organocarbonate shells show the demise of theShow More Summary

On the causes of mass extinctions

The temporal link between large igneous province (LIP) eruptions and at least half of the major extinctions of the Phanerozoic implies that large scale volcanism is the main driver of mass extinction. Here we review almost twenty biotic crises between the early Cambrian and end Cretaceous and explore potential causal mechanisms. Most extinctions are associated […]
