‘Sea butterflies’ are part of effort to better understand changing oceans

WOODS HOLE, Mass. — For Gareth Lawson, the tiny water creatures known as “sea butterflies” might offer insight into one of the biggest problems to confront the world’s oceans. Lawson is a biologist at the Woods Hole Oceanographic Institution, a private nonprofit across the water from Martha’s Vineyard. Sea butterflies – formally known as pteropods […]

Declinate in Oceanic Sulfate During Calymmian MesoProterozoic

Decline in oceanic sulfate levels during the early MesoproterozoicAuthors:Luo et alAbstract:Multiple-sulfur isotope compositions (32S, 33S, 34S and 36S) were analyzed for paired carbonate-associated sulfate (CAS) and disseminated pyrite...Show More Summary

Testing Matt Ridley’s Hypotheses About Global Warming

Matt Ridley has written an opinion piece for The Times (not the New York Times, the other one) which is a response to his critics, specifically, to those who openly disagree with him about climate change. Ridley’s commentary is jaw dropping, and for most of you, those who are not of Royal Blood and highly…

Where did the Water Come From in the Martian Late Noachian “Icy Highlands” Model

Sources of water for the outflow Channels on Mars: Implications of the Late Noachian “Icy Highlands” Model for Melting and Groundwater Recharge on the Tharsis RiseAuthors:Cassenelli et alAbstract:From the Late Noachian period, through the Hesperian, and into the Amazonian periods on Mars, large outflow channels were formed.

Prehistoric Prognostications 2014: The Results

At the end of 2013, we called for predictions for the palaeontological discoveries of 2014, and due to my pathetic love affair with alliteration, we called the post Prehistoric Prognostications. After the LITC crew made their guesses, we compiled those from commenters. Show More Summary

Sixth Mass Extinction Academic Bun Fight: Tracking Ecological Change in Egypt Over 6k Years

Collapse of an ecological network in Ancient Egypt Authors:Yeakel et alAbstract:The dynamics of ecosystem collapse are fundamental to determining how and why biological communities change through time, as well as the potential effects of extinctions on ecosystems. Show More Summary

Color Vision in the Paleozoic: Fossil Cones and Rods Found in Gzhelian Pennsylvannian Carboniferous Fish

The finding reveals that such eye cells have existed for at least 300 million years, and that the ancient fish they were discovered in likely saw in color, according to the study's scientists.Human vision depends on pigments that absorb light. Show More Summary

Hedy Lamarr

Just a note to celebrate the life and times of Hedy Lamarr, who died on this day, 2000, at the age of 85. Lamarr had a very interesting career that involved major acting accomplishments, milestone acting events, and direct involvement in the invention of the technology that now forms the basis of WiFi, BlueTooth and…

COP20: What goes into the air, goes into the ocean (video)

This event features a series of six informative and entertaining rapid talks, making the case that ocean acidification is a compelling reason to reduce carbon dioxide emissions immediately. The talks include several short videos on ocean acidification. Ocean acidification emerged as a priority out of the RIO+20 Summit and the Our Ocean Conference hosted by […]

COP20: Carol Turley, Plymouth Marine Laboratory (video)

COP20 (08/12/14) – Turley explains that ocean acidification is occurring at the fastest rate ever in Earth’s history with significant impacts on marine organisms. As 1 billion people depend on marine protein as a main protein source and engage in aquaculture for their livelihoods, adaptation is an important issue. Oceans are at the forefront of […]

Collaborative research on ocean acidification benefits Oregon

George Waldbusser, an assistant professor in the College of Earth, Ocean and Atmospheric Sciences, found his interest in the ocean and environment years ago as an undergraduate at St. John’s University in New York. “I worked on oyster recruitment as part of an effort to restore habitat around New York City,” Waldbusser said. “I ended […]

Lithium isotopes in foraminifera shells as a novel proxy for the ocean dissolved inorganic carbon (DIC)

Past ocean pH and pCO2 are critical parameters for establishing relationships between Earth’s climate and the carbon cycle. Previous pCO2 estimates are associated with large uncertainties and are debated. In this study, laboratory cultures...Show More Summary

Salinity from space unlocks satellite-based assessment of ocean acidification

Approximately a quarter of the carbon dioxide (CO2) that we emit into the atmosphere is absorbed by the ocean. This oceanic uptake of CO2 leads to a change in marine carbonate chemistry resulting in a decrease of seawater pH and carbonate ion concentration, a process commonly called ‘Ocean Acidification’. Salinity data are key for assessing […]

Transgenerational acclimation of fishes to climate change and ocean acidification

There is growing concern about the impacts of climate change and ocean acidification on marine organisms and ecosystems, yet the potential for acclimation and adaptation to these threats is poorly understood. Whereas many short-termShow More Summary

Get ready for endlessly gross shrimp, thanks to climate change

You may not think you care much about the mental well-being of imperiled sea spawn, but did ya know that a stressed-out shrimp does not a delicious cocktail make? According to a study published in November by Sweden’s University of Gothenburg, shrimp grown in acidic waters simply aren’t as tasty as those reared in healthy seas. […]

Ocean acidification along the 24.5°N section in the subtropical North Atlantic

Ocean acidification is directly related to increasing atmospheric CO2 levels due to human activities and the active role of the global ocean in absorbing part of this anthropogenic CO2. Here we present an assessment of the pH changes that have occurred along 24.5°N in the Subtropical North Atlantic through comparison of pH observations conducted in […]
