Hark! A shark! In a forest with no bark! This is no lark—a stark porthole into the dark reveals a leopard strolling through the seaweed park. Mark these words with no snark, the arc of the window leaves this shark in its nucleus like a quark. Thanks to Instagrammer @formicaphoto for the snap!

Maine’s coastal waters are unhealthy from carbon, acidity. Are seaweed gardens the answer?

BOOTHBAY, Maine — Seaweed cultivation has been promoted in recent years in Maine as a way to produce local nutritious food and to boost the coastal economy. Now, seaweed harvesters say their industry provides yet another benefit: environmental protection, in the form of improving water quality. A new study from Bigelow Laboratory for Marine Sciences […]

Effects of ocean acidification on the potency of macroalgal allelopathy to a common coral

Many coral reefs have phase shifted from coral to macroalgal dominance. Ocean acidification (OA) due to elevated CO2 is hypothesised to advantage macroalgae over corals, contributing to these shifts, but the mechanisms affecting coral-macroalgal interactions under OA are unknown. Here, we show that (i) three common macroalgae are more damaging to a common coral when […]

The most primitive metazoan animals, the placozoans, show high sensitivity to increasing ocean temperatures and acidities

The increase in atmospheric carbon dioxide (CO2) leads to rising temperatures and acidification in the oceans, which directly or indirectly affects all marine organisms, from bacteria to animals. We here ask whether the simplest—andShow More Summary

Skeletal dissolution kinetics and mechanical tests in response to morphology among coral genera

Ocean acidification is widely accepted as a primary threat to coral reef populations. Negative physiological effects include decreased calcification rates, heightened metabolic energy expenditure, and increased dissolution of coral skeletons. Show More Summary

Kelp and carbon: pathways and barriers to acquisition and transport

Large brown algae in the class Phaeophyceae (Heterokontophyta) form the structural and energetic foundation of temperate and subtropical nearshore marine forests of high productivity and ecological diversity. This dissertation examines...Show More Summary

How ocean acidification can benefit calcifiers

Reduction in seawater pH due to rising levels of anthropogenic carbon dioxide (CO2) in the world’s oceans is a major force set to shape the future of marine ecosystems and the ecological services they provide 1 and 2. In particular, ocean acidification is predicted to have a detrimental effect on the physiology of calcifying organisms […]

Assessment of ocean acidification and warming on the growth, calcification, and biophotonics of a California grass shrimp

Cryptic colouration in crustaceans, important for both camouflage and visual communication, is achieved through physiological and morphological mechanisms that are sensitive to changes in environmental conditions. Consequently, ocean...Show More Summary

BIOACID Science Portrait: Lennart Bach – “Emiliania huxleyi – A tiny alga with a large impact”

Lennart Bach, marine biologist at GEOMAR Helmholtz Centre for Ocean Research Kiel investigates a tiny organism that can hardly be seen with the naked eye – and is still visible from space. The single-celled calcifying alga that his research focuses on is called Emiliania huxleyi. It is a true multi-talent: Its calcium carbonate platelets carry […]

Molecular response of Sargassum vulgare to acidification at volcanic CO2 vents – insights from de novo transcriptomic analysis

Ocean acidification is an emerging problem that is expected to impact ocean species to varying degrees. Currently, little is known about its effect on molecular mechanisms induced in fleshy macroalgae. To elucidate genome wide responses...Show More Summary

Ocean Sunfish are the most useless animal (an epic rant)

Ocean Sunfish, also known as Mola Mola, look like a pancake and are just the weirdest fish. I was ambivalent about these creatures until reading this absolutely EPIC Facebook rant about their sheer uselessness – and now I can’t help but LOL wondering how they even continue to exist in nature. Mola Mola – the Pandas […]

A video posted by Monterey Bay Aquarium (@montereybayaquarium) on Feb 6, 2017 at 2:47pm PST Jellies come in all shapes and stripes—in this case, purple ones! Purple-striped jellies can grow quite large, with their bells reaching up to three feet wide and the tentacles extending to 25 feet!

Happy one-year-anniversary at Shedd Aquarium to Ellie, seen here when she was still known as pup 719! Visit Shedd’s Facebook page to see how much she’s grown. Huge thank you to our members and donors, whose support made her rescue (and all the work of our Sea Otter Program) possible. Learn more about Ellie’s story and the work of our Sea Otter Program:

Inter- and intraspecific phenotypic plasticity of three phytoplankton species in response to ocean acidification

Phenotypic plasticity describes the phenotypic adjustment of the same genotype to different environmental conditions and is best described by a reaction norm. We focus on the effect of ocean acidification on inter- and intraspecificShow More Summary

Variation in carbonate system and air-water CO2 flux during summer in the Mahanadi Estuary, India

The carbonate system of water of the inner estuary and near shore in the Mahanadi estuary, Bay of Bengal, India was studied in summer season of 2014. Physicochemical parameters like temperature, pH, salinity, total alkalinity (TA), dissolved...Show More Summary

Geographical gradients in selection can reveal genetic constraints for evolutionary responses to ocean acidification

Geographical gradients in selection can shape different genetic architectures in natural populations, reflecting potential genetic constraints for adaptive evolution under climate change. Investigation of natural pH/pCO2 variation in...Show More Summary
