Nap time! Elephant seals migrate thousands of miles, dive to over a mile deep and hold their breath for up to two hours. After all of that, they deserve some R&R. (The pups are just practicing.)

amnhnyc: Happy #ManateeAppreciationDay! Gentle and solitary, West Indian manatees, Trichechus manatus, wander through both fresh and salt water. They keep to warm regions because they have no blubber, which insulates other marine mammals living in colder climates. Show More Summary

How do higher CO2 levels impact marine life?

As the concentration of carbon dioxide (CO2) in the atmosphere continues to climb, a group of researchers at Lamont-Doherty Earth Observatory are investigating how this change will impact the Earth system, with a focus on oceans and marine life. Show More Summary

Climate change is the greatest environmental challenge of our time—now is the time to speed up, not reverse, the progress being made by legislation like the Clean Power Plan. The Monterey Bay Aquarium will continue to advocate for science-based public policies to address the threats to society posed by climate change.  Read the full statement from our Director, Julie Packard.

Sunny skies and blue waves make for a lovely day on the Monterey Bay today. Keep an eye out for passing seabirds, seals and sea otters! This lovely stretch of blue is part of the Monterey Bay National Marine Sanctuary (shoutout to @noaasanctuaries!),...Show More Summary

noaasanctuaries: She said what??  Here, two northern elephant seal pups play-fight on the beach in Monterey Bay National Marine Sanctuary.  Though they can be fun to watch, it’s crucial that you give these animals plenty of space – it’s safer for both you and them. Show More Summary

Core-top calibration of B/Ca in Pacific Ocean Neogloboquadrina incompta and Globigerina bulloides as a surface water carbonate system proxy

Practical methods for reconstructing past ocean carbonate chemistry are needed to study past periods of ocean acidification and improve understanding of the marine carbonate system’s role in the global climate cycles. Planktic foraminiferal B/Ca may fill this role, but requires better understanding and improved proxy calibrations. Show More Summary

Alleviation of mercury toxicity to a marine copepod under multigenerational exposure by ocean acidification

Ocean acidification (OA) may potentially modify the responses of aquatic organisms to other environmental stressors including metals. In this study, we investigated the effects of near-future OA (pCO2 1000??atm) and mercury (Hg) on the development and reproduction of marine copepod Tigriopus japonicus under multigenerational life-cycle exposure.

High levels of solar radiation offset impacts of ocean acidification on calcifying and non-calcifying strains of Emiliania huxleyi

Coccolithophores, a globally distributed group of marine phytoplankton, showed diverse responses to ocean acidification (OA) and to combinations of OA with other environmental factors. While their growth can be enhanced and calcification...Show More Summary

Climate change can cause complex responses in Baltic Sea macroalgae: A systematic review

Estuarine macroalgae are important primary producers in aquatic ecosystems, and often foundation species providing structurally complex habitat. Climate change alters many abiotic factors that affect their long-term persistence and distribution. Show More Summary

Update from the deep sea!

Our colleagues at Monterey Bay Aquarium Research Institute (MBARI) have only seen the Haliphron atlanticus octopus three times in 27 years.  Recently they spotted one carrying an egg-yolk jelly and made a discovery about this elusive...Show More Summary

Nothing looks quite as cozy as a seal napping on a beach. But when elephant seals visit Año Nuevo State Park every December-March, they’re not the just resting. They’ve got important work to do!

3-28-17 Ship Noise

'A Key to Quieter Seas: half the ship noise comes from 15% of the fleet (deep sea vessels). For someone who listens to the hydrophones just about 24/7 and 365, this document is awesome. It's a must read about ships and the noise they are creating and impacts it is having on sea life. Show More Summary

Pacific leaders tackle ocean acidification

If the land is well and the sea is well, the people will thrive. This adage is relevant now more than ever as climate change is encroaching on our shores. Leaders from around the Pacific have joined in to tackle the issue of climate change specifically focusing on ocean acidification. Last week, was the opening of the […]

Effects of CO2 concentration on a late summer surface sea ice community

Annual fast ice at Scott Base (Antarctica) in late summer contained a high biomass surface community of mixed phytoflagellates, dominated by the dinoflagellate, Polarella glacialis. At this time of the year, ice temperatures rise close to melting point and salinities drop to less than 20. At the same time, pH levels can rise above 9 […]

Development of an economical, autonomous pHstat system for culturing phytoplankton under steady state or dynamic conditions

Laboratory investigations of physiological processes in phytoplankton require precise control of experimental conditions. Chemostats customized to control and maintain stable pH levels (pHstats) are ideally suited for investigations of the effects of pH on phytoplankton physiology, for example in context of ocean acidification.

Ocean acidification increases larval swimming speed and has limited effects on spawning and settlement of a robust fouling bryozoan, Bugula neritina

Few studies to date have investigated the effects of ocean acidification on non-reef forming marine invertebrates with non-feeding larvae. Here, we exposed adults of the bryozoan Bugula neritina and their larvae to lowered pH. We monitored spawning, larval swimming, settlement, and post-settlement individual sizes at two pHs (7.9 vs. Show More Summary

Abstract submission open: “Climate Change and High CO2 Effects on Fishes: Moving from Individual to Community Level Effects”, 10th Indo-Pacific Fish Conference, 2-6 October 2017, Tahiti, French Polynesia

Deadline for abstract submission: 22 July 2017! Convenors: Ivan Nagelkerken, Philip Munday, Colin Brauner & Marc Metian Description: We have entered an era of increasing uncertainty about the effect of human activities on the function and services of marine and freshwater ecosystems.
