Roger Norman Bamber (1949-2015)

I asked Tammy Horton, a noted expert on crustaceans, to write this post about the life of her colleague and friend Roger. Roger will be greatly missed in the community both for his scientific contributions and his companionship. Roger Norman Bamber (1949-2015) I am proud to have been given the task of writing this farewell […]

It’s an eggstravaganza! Our rescued sea otters are pros at cracking open these icy Easter eggs—just like their wild kin who chomp on urchins and keep kelp forests healthy. Tune in to our otter cam

Seaweed fails to prevent ocean acidification impact on foraminifera along a shallow-water CO2 gradient

Ocean acidification causes biodiversity loss, alters ecosystems, and may impact food security, as shells of small organisms dissolve easily in corrosive waters. There is a suggestion that photosynthetic organisms could mitigate ocean...Show More Summary

Quasimeme Workshop on Quality Assurance for inorganic carbon system measurements in context of ocean acidification monitoring

Timing and venue: 19th-21st May 2015; National Oceanography Centre, Southampton (NOC), UK Organisers: Susan Hartman and Caroline Kivimae, NOC / Pam Walsham, Marine Scotland Science, Koen Parmentier, MUMM and Joop Harmsen Alterra Wageningen UR Aims of the workshop 1. Show More Summary

Response of key stress-related genes of the seagrass Posidonia oceanica in the vicinity of submarine volcanic vents

Submarine volcanic vents are being used as natural laboratories to assess the effects of CO2 on marine organisms and communities, as this gas is the main component of emissions. Seagrasses should positively react to increased dissolved carbon, but in vicinity of volcanic vents there may be toxic substances, that can have indirect effects on seagrasses. […]

Ocean acidification and cellular metabolism

Ocean acidification may increase the amount of metabolic energy necessary for marine organisms to maintain normal cell functions, according to a study. Although the effect of ocean acidification on whole organism growth appears to be minimal, reduced seawater pH may impose a metabolic cost. Donal T. Manahan and colleagues grew larvae of sea urchins under […]

4-1-15 We Know Who Our Moms Are!

Wednesday, April 1 First I need to clarify: I am not a researcher. Somewhere along the way in the last few days that got added by my name, one of the images of J-52 (now official) Just posted from the Center for Whale Research the 'surprise baby' from March 30th. Show More Summary

Experimental ocean acidification alters the allocation of metabolic energy

Energy is required to maintain physiological homeostasis in response to environmental change. Although responses to environmental stressors frequently are assumed to involve high metabolic costs, the biochemical bases of actual energy demands are rarely quantified. Show More Summary

Ocean acidification spells trouble for shellfish industry

If mollusks, particularly the shelled and delicious variety, can feel emotions, then they must be getting nervous. Not of happy hour regulars eyeing the one-dollar oysters, mind you, but of the creeping acidity in the oceans. According to a new study, clams, mussels, oysters and their brethren shouldn’t be the only ones feeling anxious, because […]

Sniffer dogs to transform the aquaculture industry

A recent breakthrough by scientists at the University of Poisson, Canada has discovered the use of sniffer dogs in the detection of acidification in water samples. Although the training and research is ongoing, the university has released promising data suggesting a 98% success rate in the detection of subtle changes in water acidity. Dogs have […]

Acidification

This chapter outlines the cause-effect pathway of terrestrial and aquatic acidification from air emissions to ecosystem damage. Carbon dioxide is the main cause of (coastal) marine acidification, while nitrogen and sulfur inputs are underlying the damage due to freshwater and terrestrial acidification. Show More Summary

Effect of simulated ocean acidification on chitin content in the shell of white shrimp, Litopenaeus vannamei

This study examined the effect of simulated ocean acidification on chitin content in the shell of marine white shrimp,Litopenaeus vannamei. The experiment was conducted in tanks where a change in carbonate chemistry characterizing theocean acidification related to climate change was induced by supplying the exogenous carbon dioxide to the sea water.

It’s Time to Overhaul the Funding of Ocean Science

The National Research Council (NRC) released the first-ever Decadal Survey of Ocean Sciences(DSOS) report on 23 January 2015 as commissioned by the National Science Foundation’s (NSF) Division of Ocean Sciences (OCE).  The 147 page report...Show More Summary

The ecology of ocean acidification: integrating the effects of pH variation among other environmental stressors on biogeography and organismal performance in rocky intertidal communities

Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleteriousShow More Summary
