If John Steinbeck had been a diver, the novel might have been “The Sea Grapes of Wrath”! Sea grapes are filled with a mucous-like fluid which buoys their branches up, helping them compete for light. Happy Seaweed Sunday!

Rare, adorable, invisible ghost nautilus invades Aquarium tide pool!

Aquarium patrons gather to see the cute, if intangible, visitor. Said one staffer: “If you don’t see it, that’s what it looks like!” Monterey, CA — For the first time in its 32 years, the Monterey Bay Aquarium’s open-ocean Great Tide Pool is playing host to an uncommon, charming and completely invisible ghost nautilus.

Why managing ocean acidification is crucial for South Africa

The southern tip of Africa is washed by two oceans: the Indian and Atlantic oceans. This should allow South Africa to benefit economically from various activities through developing the ocean economy. Fisheries, tourism and maritime activities are some of the sectors that can underpin the economy. There is enormous potential for countries with an ocean […]

Breakthrough in the ocean acidification adaptation strategies? Smart fabric to protect large marine molluscs from increased seawater acidity

The International Textiles Federation (ITF) recently revealed the “hot” topic of its upcoming Smart Fabric Symposium to be held on 1-2 April 2016 in Poissons, eastern France. The discussions will be centered around a revolutionary smart fabric developed in response to the threat of ocean acidification to mollusks – an important component of marine ecosystems […]

Biomarker response of ocean acidification induced hypercapnia on marine bivalve Donax cuneatus, Linnaeus 1758

The present study reports the investigation of the sub lethal impacts of ocean acidification induced hypercapnia (pH 7.5 and 7.0) and leakage of sub sea bed Carbon Dioxide storage sites (pH 6.5-5.5) on marine bivalve Donax cuneatus, Linnaeus 1758 collected from the Gulf of Mannar province. Fifteen days experiment was carried out in laboratory microcosms […]

What is ocean acidification and why is it worse at night?

Ocean acidification is the chemical process that is set into motion when the Earth’s oceans, lakes, and rivers absorb atmospheric carbon dioxide produced by automobiles, airplanes, and power plants (doi:10.1146/annurev.marine.010908.163834). Show More Summary

We’re spotting pigeon guillemots off the back deck! These shorebirds visit us in the spring, when they pair off together and perform a courtship “water dance”—calling, diving and chasing each other. Fun fact: Predicting the arrival date of the first pigeon guillemot of the spring is an annual tradition for Aquarium staffers!  Learn more about pigeon guillemots

Plastic and evolved responses to global change: what can we learn from comparative transcriptomics?

Physiological plasticity and adaptive evolution may facilitate persistence in a changing environment. As a result, there is an interest in understanding species’ capacities for plastic and evolved responses, and the mechanisms by which these responses occur. Show More Summary

Ocean acidification and increased temperature have both positive and negative effects on early ontogenetic traits of a rocky shore keystone predator species

The combined effect of ocean acidification and warming is expected to have significant effects on several traits of marine organisms. The gastropod Concholepas concholepas is a rocky shore keystone predator characteristic of the south-eastern...Show More Summary

Two California fishermen pretend they are maritime pirates and hold an oceanographic mooring for ransom

First, let’s give a shoutout to these two dudes who found a washed up mooring and, like adults, gave it back to MBARI. Now I give the eye of disdain to another two fisherman, who found a detached piece of an mooring and have decided to hold it for ransom. It’s not unusual that oceanographic moorings […]

Scalloped hammerhead sharks can grow to 14 feet, munching on a diet of fishes, squid, crustaceans and stingrays. One especially persevering hammerhead was found with 96 venomous stingray barbs embedded in its mouth and jaws!  You can spot our scalloped hammerhead sharks on our Open Sea Cam!

Keating leads discussion on ocean acidification problem

WOODS HOLE – A meeting organized by 9th District Congressman Bill Keating brought together fellow lawmakers, marine industry representatives and environmental activists Monday for a round table discussion regarding ocean acidification. Show More Summary

PhD scholarship: “Using stable isotope tracers to determine the impact of climate-related stressors on carbon and nitrogen cycling”, Southern Cross University, Australia

Deadline for applications: 18 April 2016! Shallow-water sediments at the land-sea interface are dynamic sites of carbon and nitrogen processing and therefore play a significant role in oceanic biogeochemical cycling. These processes can, however, be impacted by environmental conditions. Show More Summary

Effects of future climate conditions on photosynthesis and biochemical component of Ulva pertusa (Chlorophyta)

Ulva pertusa, a common bloom-forming green alga, was used as a model system to examine the effects of elevated carbon dioxide (CO2) and temperature on growth and photosynthetic performance. To do this, U. pertusa was grown under four temperature and CO2 conditions; ambient CO2 (400 ?atm) and temperature (16°C) (i.e., present), elevated temperature only (19°C) […]

Restructuring of epibacterial communities on Fucus vesiculosus forma mytili in response to elevated pCO2 and increased temperature levels

Marine multicellular organisms in composition with their associated microbiota – representing metaorganisms – are confronted with constantly changing environmental conditions. In 2110, the seawater temperature is predicted to be increased...Show More Summary

Life under climate change scenarios: sea urchins’ cellular mechanisms for reproductive success

Ocean Acidification (OA) represents a major field of research and increased efforts are being made to elucidate its repercussions on biota. Species survival is ensured by successful reproduction, which may be threatened under detrimental environmental conditions, such as OA acting in synergy with other climate change related stressors.

Using present-day observations to detect when anthropogenic change forces surface ocean carbonate chemistry outside pre-industrial bounds

One of the major challenges to assessing the impact of ocean acidification on marine life is the need to better understand the magnitude of long-term change in the context of natural variability. This study addresses this need through a global synthesis of monthly pH and aragonite saturation state (?arag) climatologies for 12 open ocean, coastal, […]

Are global warming and ocean acidification conspiring against marine ectotherms? A meta-analysis of the respiratory effects of elevated temperature, high CO2 and their interaction

With the occurrence of global change, research aimed at estimating the performance of marine ectotherms in a warmer and acidified future has intensified. The concept of oxygen- and capacity-limited thermal tolerance, which is inspired...Show More Summary
