Where is the best place to put your ocean cleanup device? Not where currently proposed.

You might think that to clean up the problem of plastic in the ocean, you should place your cleanup device where there is the most plastic. And this isn’t a horrible initial assumption, which has been made by “The Ocean Cleanup”. But a slick new modeling study by Peter Sherman and Erik van Sebille show […]

Der kleine Bruder des Klimawandels (audio & text, in German)

Der ph-Wert der Meere sinkt. Seit Beginn der Industrialisierung haben die Ozeane knapp die Hälfte des Kohlendioxids aus der Verbrennung fossiler Energieträger aufgenommen. Welche Folgen die Versauerung für Meeresorganismen hat, untersucht ein Kieler Forscherteam. Show More Summary

An integrated coral reef ecosystem model to support resource management under a changing climate

Millions of people rely on the ecosystem services provided by coral reefs, but sustaining these benefits requires an understanding of how reefs and their biotic communities are affected by local human-induced disturbances and global climate change. Show More Summary

A multi-proxy approach to decode the end-Cretaceous mass extinction

Mass extinctions generally involve a complex array of interrelated causes and are best evaluated by a multi-proxy approach as applied here for the end-Cretaceous mass extinction. This study documents and compares the planktic foraminiferal...Show More Summary

Ocean acidification decreases plankton respiration: evidence from a mesocosm experiment

Anthropogenic carbon dioxide (CO2) emissions are reducing the pH in the world’s oceans. The plankton community is a key component driving biogeochemical fluxes, and the effect of increased CO2 on plankton is critical for understanding the ramifications of ocean acidification on global carbon fluxes.

Effects of ocean acidification on developmental thermal windows of echinoderms

Under future ocean warming, thermal tolerance of developmental stages may be a key driver of changes in the geographical distributions and abundance of marine invertebrates. Additional stressors such as ocean acidification may influence thermal windows and are therefore important considerations under realistic future climate change scenarios. Show More Summary

Intra-skeletal calcite in a live-collected Porites sp.: Impact on environmental proxies and potential formation process

Geochemical proxies measured in the carbonate skeleton of tropical coral Porites sp. have commonly been used to reconstruct sea surface temperature (SST) and more recently seawater pH. Nevertheless, both reconstructed SST and pH depend on the preservation state of the skeleton, here made of aragonite; i.e., diagenetic processes and its related effects should be limited. […]

Reduced resilience of a globally distributed coccolithophore to ocean acidification: Confirmed up to 2000 generations

Ocean acidification (OA), induced by rapid anthropogenic CO2 rise and its dissolution in seawater, is known to have consequences for marine organisms. However, knowledge on the evolutionary responses of phytoplankton to OA has been poorly studied. Show More Summary

The effects of arsenic and seawater acidification on antioxidant and biomineralization responses in two closely related Crassostrea species

Ocean acidification processes are major threats to marine calcifying organisms, mostly affecting biomineralization related processes. Abiotic stressors acting on marine systems do not act alone, rather in a combination of multiple stressors, especially in coastal habitats such as estuaries, where anthropogenic and environmental pressures are high.

The Monterey Bay Aquarium is the only aquarium in North America to display bluefin tuna! While the world’s top bluefin experts and stakeholders assemble for day two of the Bluefin Future’s Symposium, watch these fabulous fish swim in our Open Sea exhibit.

Hey girl hey! Welcome African black-footed penguin Elizabeth to our exhibit!

Easy, breezy, beautiful… Feather Girl. Let’s put our wings together to welcome Elizabeth, our new African black-footed penguin! Named after Port Elizabeth in South Africa, she’s seven years old and came to us from the Knoxville Zoo.  “She’s a sweet bird. Show More Summary

Effect of ocean acidification on the structure and fatty acid composition of a natural plankton community in the Baltic Sea

Increasing atmospheric carbon dioxide (CO2) is changing seawater chemistry towards reduced pH, which consequently affects various properties of marine organisms. Coastal and brackish water communities are expected to be less affected by ocean acidification (OA) as these communities are typically adapted to high fluctuations in CO2 and pH. Show More Summary

Effects of in situ CO2 enrichment on structural characteristics, photosynthesis, and growth of the Mediterranean seagrass Posidonia oceanica

Seagrass are expected to benefit from increased carbon availability under future ocean acidification. This hypothesis has been little tested by in situ manipulation. To test for ocean acidification effects on seagrass meadows under controlled CO2/pH conditions, we used a Free Ocean Carbon Dioxide Enrichment (FOCE) system which allows for the precise manipulation of pH as […]

Non-linear effects of ocean acidification on the transmission of a marine intertidal parasite

High levels of atmospheric carbon dioxide are driving the acidification of the world’s oceans, with considerable and generally negative impacts on the physiology, performance and survival of marine organisms. The differential and often...Show More Summary

Community metabolism in shallow coral reef and seagrass ecosystems, lower Florida Keys

Diurnal variation of net community production (NEP) and net community calcification (NEC) were measured in coral reef and seagrass biomes during October 2012 in the lower Florida Keys using a mesocosm enclosure and the oxygen gradient flux technique. Seagrass and coral reef sites showed diurnal variations of NEP and NEC, with positive values at near-seafloor […]

exploratorium: How a Warm Water Blob Upset Life Across the Pacific The Exploratorium blogged this story twice in 2015, but we think it still counts as unsung science, since El Nino grabbed so much of this year’s ocean news. To review: there’s been a giant blob of unusually warm ocean water parked just south of Alaska since early 2014. Show More Summary

1-18-15 Mid January Update

Monday, January 18th -There are never the right words to say. The passing of Eva Saulitis, a whale researcher of the Chugach Transients, of Prince William Sound, Alaska, author of many books, most recent Into Great Silence. From reading her account of 25 years, I felt like I knew Eva, yet met her only briefly in Friday Harbor in the fall of 2014. Show More Summary

Julie Packard on shaping a bright future for bluefin tunas

Julie Packard on shaping a bright future for bluefin tunas: The Bluefin Futures Symposium kicks off today right here in Monterey! Together, the participants are working to create a roadmap toward healthy and sustainable wild bluefin tuna populations around the world. Aquarium Executive Director Julie Packard opened the symposium with these thoughts:

We’ve spotted long-beaked common dolphins from our back deck! Often seen in huge groups, these sleek swimmers can churn up the surface of the water so much that it looks like it’s boiling. The Sicilian fishermen who settled in Monterey...Show More Summary

Megafauna and Minerals on the Pacific Abyss

This guest post is from Dr. Diva Amon (on Twitter @DivaAmon). Dr. Amon is marine biologist specialising in deep-sea biology, working on a range of environments, from abyssal plains to chemosynthetic habitats.
