[Oyster_seed_group] Aug 9, 2011 Willapa Oyster Bulletin
By Alan Trimble Oyster Bulletin No. 4 – 9 August 2011 Monday’s oyster larvae counts are diminished from 4 days previously, and the larvae are still at very early stages. Average size is about 100 microns, compared to 90 microns last Friday. Standard growth is 10 microns per day, so
Impact of CO2-acidified seawater on the extracellular acid–base balance of the northern sea urchin Strongylocentrotus dröebachiensis
Posted on EPOCA: 08 Aug 2011 — Highlights ► Hypercapnia exposed sea urchins did not compensate for an internal acidification. ► This internal acidosis increased in intensity with decreasing environmental pH. ► This was similar to P. miliaris despite marked differences in seawater carbonate. This study highlights the need for

By Alan Trimble — Oyster_seed_group mailing list Oyster_seed_group@lists.oregonstate.edu http://lists.oregonstate.edu/mailman/listinfo/oyster_seed_group Oyster Bulletin No. 3 – 6 August 2011 We sampled for larvae on Tuesday 2 August (afternoon high tide) and Friday 5 August (morning high tide). Water temperatures have been steady over the past week, given the calm conditions with cloud
Calcifying microalgae are witnesses of increasing ocean acidification
Posted on EPOCA: 04 Aug 2011 For the first time researchers have examined on a global scale how calcified algae in their natural habitat react to increasing acidification due to higher marine uptake of carbon dioxide. In the current issue of the magazine Nature they explain that Coccolithophores, a
