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 […]

2-6-17 A Snow Day and Whale Day Too!

Monday, February 6th...catching up on what J Pod has been doing...that large group of transients had gone up island on February 2nd (previous post)......J Pod came down the next day (Feb 3rd), down San Juan Channel at about More Summary

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

Transcriptomic responses to seawater acidification among sea urchin populations inhabiting a natural pH mosaic

Increasing awareness of spatial and temporal variation in ocean pH suggests some marine populations may be adapted to local pH regimes and will therefore respond differently to present-day pH variation and to long-term ocean acidification. Show More Summary

How ocean acidification contributes to underwater fife formation?

Under high trial CO2 conditions, the shells of mollusks, clams, and a few snails and urchins are mostly dissolved partly. Most recent research has yielded astonishing discoveries about how the shells of marine life forms may face an undeniably acidic sea later on. As reported in ScienceDaily, a group of scientists from the NIOZ (Royal […]

Carbonate system biogeochemistry in a subterranean estuary – Waquoit Bay, USA

Quantifying carbon fluxes associated with submarine groundwater discharge (SGD) remains challenging due to the complex biogeochemistry of the carbonate system in the subterranean estuary (STE). Here we conducted time series measurements...Show More Summary

Sensitivity towards elevated pCO2 in great scallop (Pecten maximus Lamarck) embryos and fed larvae (update)

The increasing amount of dissolved anthropogenic CO2 has caused a drop in pH values in the open ocean known as ocean acidification. This change in seawater carbonate chemistry has been shown to have a negative effect on a number of marine organisms. Early life stages are the most vulnerable, and especially the organisms that produce […]

Individual and interactive effects of warming and CO2 on Pseudo-nitzschia subcurvata and Phaeocystis antarctica, two dominant phytoplankton from the Ross Sea, Antarctica

We investigated the effects of temperature and CO2 variation on the growth and elemental composition of cultures of the diatom Pseudo-nitzschia subcurvata and the prymnesiophyte Phaeocystis antarctica, two ecologically dominant phytoplankton species isolated from the Ross Sea, Antarctica.
