11-18-17 Lime Kiln Hydrophones From Overload to Complete Silence!

Friday and Saturday, November 17th and 18th Friday:...when I was awakened at about 3:00 a.m. to a humpback making sounds over the Lime Kiln hydrophones, the sounds were intermittent, and it didn't sound like practicing a song...but the...Show More Summary

11-16-17 J Pod Was Here Today !

Thursday, November 16th...I had been thinking about when the whales showed up the day before and the day of Thanksgiving in 2013...and then I thought about how I almost had a scheduled today to dig into some archives with someone......well,...Show More Summary

Public Sea Turtle Release 11/18

We survived Irma and have something to celebrate! Please join us for a public sea turtle release Saturday November 18th at Sombrero Beach in Marathon at 10:30 am! Bring your family and friends! Judah, an 80 pound sub-adult loggerhead sea turtle was rescued off of Islamorada oceanside in July where the Hill family found him […]

CARIOCA project – coral reef acclimatization to ocean acidification (video; in French and in English)

In the framework of the project CARIOCA (Coral reef acclimatization to ocean acidification at CO2 seeps) funded by the French National Agency ANR, Riccardo Rodolfo-Metalpa and the team IRD Entropie investigated a new promising CO2 vents system located in Papua New Guinea. This site was explored by a team of geologists 20 years ago (Pichler […]

Das andere CO2-Problem (video; in German)

Wissenschaftler beenden achtjähriges Projekt zur Ozeanversauerung: Zuviel Kohlendioxid lässt weltweit die Ozeane versauern. Meeres-Forscher des Netzwerkes BIOACID warnen vor den dramatischen Auswirkungen. 3sat Mediathek, 14 November 2017. Video.  Filed under: Media coverage

The future of seaweed aquaculture in a rapidly changing world

Human activities are having increasingly negative impacts on the natural environment. The rapidly expanding human population has led to a shortage of resources and the ability to support the growing population sustainably is a major challenge for the future. Show More Summary

Effects of high pCO2 on early life development of pelagic spawning marine fish

The present study investigated the effect of elevated pCO2 on the development of early stages of the pelagic spawning marine fish Solea senegalensis, Diplodus sargus and Argyrosomus regius. Eggs and larvae were reared under control (pH 8.0, ~570 ?atm) and two elevated pCO2 conditions (pH 7.8, ~1100 ?atm; pH 7.6, ~1900 ?atm) until mouth opening (3 days post-hatching). […]

Diversity and stability of coral endolithic microbial communities at a naturally high pCO2 reef

The health and functioning of reef-building corals is dependent on a balanced association with prokaryotic and eukaryotic microbes. The coral skeleton harbours numerous endolithic microbes, but their diversity, ecological roles and responses to environmental stress, including ocean acidification (OA), are not well characterized.

Aragonite saturation state in a tropical coastal embayment dominated by phytoplankton blooms (Guanabara Bay – Brazil)

Highlights The spatio-temporal variations of ?arag were studied in a highly polluted coastal embayment. High values of ?arag were prevalent in surface waters dominated by phytoplankton blooms. Lowest values of ?arag were restricted to poorly buffered waters that receive direct effluent discharges. Show More Summary

The role of natural variability in shaping the response of coral reef organisms to climate change

Purpose of Review We investigate whether regimes of greater daily variability in temperature or pH result in greater tolerance to ocean warming and acidification in key reef-building taxa (corals, coralline algae). Recent Findings Temperature and pH histories will likely influence responses to future warming and acidification. Show More Summary

Local habitat influences on feeding and respiration of the intertidal mussels Perumytilus purpuratus exposed to increased pCO2 levels

Coastal ecosystems are exposed to changes in physical-chemical properties, such as those occurring in upwelling and freshwater-influenced areas. In these areas, inorganic carbon can influence seawater properties that may affect organisms and populations inhabiting benthic habitats such as the intertidal mussel Perumytilus purpuratus.

Multidecadal fCO2 increase along the United States southeast coastal margin

Coastal margins could be hotspots for acidification due to terrestrial-influenced CO2 sources. Currently there are no long-term (>20 years) records from biologically important coastal environments that could demonstrate sea surface CO2 fugacity (fCO2) and pH trends. Show More Summary

Seaweed Sorting? There’s Now an App for That!

“What is that squishy brown stuff on the rock?” – said every tidepool enthusiast ever. Just in time for the low winter tides, the brilliant minds of the Martone Lab out of University of British Columbia have come to the rescue (just in case you needed one more reason to love Canadia). With over 100 different […]

Alaska Ocean Acidification Network Survey

The Alaska Ocean Acidification Network is interested in your opinion and priorities.  Researchers and resources managers are monitoring ocean acidification in Alaska, and need your input to develop a build-out plan for the monitoring network. Your help will make sure the plan addresses questions that are important to Alaskans. This survey should take less than […]

Associate Research Scientist, GOA-ON support – IAEA Environment Laboratories (NAEL), Monaco

This position is part of an IOC-UNESCO/IAEA- co-hosted distributed GOA-ON Secretariat. Closing date: 19 November 2017. Position open for US citizens. Organizational Setting The Department of Nuclear Sciences and Applications implements the IAEA’s Major Programme 2, “Nuclear Techniques for Development and Environmental Protection”.

Southern Ocean pteropods at risk from ocean warming and acidification

Early life stages of marine calcifiers are particularly vulnerable to climate change. In the Southern Ocean aragonite undersaturation events and areas of rapid warming already occur and are predicted to increase in extent. Here, we present the first study to successfully hatch the polar pteropod Limacina helicina antarctica and observe the potential impact of exposure […]

Competitive interactions moderate the effects of elevated temperature and atmospheric CO2 on the health and functioning of oysters

Global increases in sea temperatures and atmospheric concentrations of CO2 may affect the health of calcifying shellfish. Little is known, however, about how competitive interactions within and between species may influence how species respond to multiple stressors. Show More Summary

Timelapse of ocean acidification effects on coral

Stanford Earth’s Cassandra Brooks contributed footage to a new interactive David Attenborough project about the Great Barrier Reef. Brook’s video shows the effects of ocean acidification on the limestone skeleton of a sand dollar.

Target gene expression studies on Platynereis dumerilii and Platynereis cfr massiliensis at the shallow CO2 vents off Ischia, Italy

Many studies predict negative effects of ocean acidification on marine organisms, potentially leading to loss of biodiversity and ecosystem function. Research on species inhabiting naturally high pCO2 environments, such as volcanic CO2 vents, offers an opportunity to understand the molecular mechanisms involved in high pCO2 regulation.

Impact of surface ocean conditions and aerosol provenance on the dissolution of aerosol manganese, cobalt, nickel and lead in seawater

Highlights Simulated ocean warming, ocean acidification and anoxia had little impact on the dissolution of aerosol Co, Mn, Ni and Pb in surface seawater Aerosol provenance and chemical speciation exerted the greatest control on Co and...Show More Summary
