Leading scientists call for more effort in tackling rising ocean acidity

_T14b — Mon, 14 Jun 2010 16:02:32 +0000

Ten years ago, ocean acidification was a phenomenon only known to small group of ocean scientists. It's now recognized as the hidden partner of climate change, prompting calls for an urgent, substantial reduction in carbon emissions to reduce future impacts. Scientists from the European Science Foundation at European Maritime Day 2010 give a comprehensive view of current research and highlight the need for a integrated effort internationally to research and monitor ocean acidification effects.... ...

Could climate change and biodiversity of marine plankton in North Atlantic affect carbon cycle?

_T14b — Mon, 14 Jun 2010 16:02:27 +0000

Over the last decades, global warming has been accompanied by an increase in the taxonomic biodiversity of phytoplankton and zooplankton in the North Atlantic Ocean and a reduction in the average size of these organisms, according to researchers. They demonstrate that this structural modification of biological systems could bring about an alteration to the carbon sink in the North Atlantic and a reduction in the presence of subarctic fish such as cod.... ...

Mon 6/14: Perspectives Lecture: "Probing Long-term Temperature Change in the Southern Ocean"

_T14a — Sun, 13 Jun 2010 16:02:31 +0000

When: Monday, June 14, 2010, 6:30 p.m. to 8 p.m.

Where: Birch Aquarium at Scripps, 2300 Expedition Way, La Jolla, CA

Cost: $8

Age limit: All ages

Description: Explore Earth’s mysteries through the Jeffrey B. Graham "Perspectives on Ocean Science" Lecture Series, presented monthly at Birch Aquarium at Scripps Institution of Oceanography, UC San Diego.

From the cosmos to the ocean abyss, join Scripps researchers on their paths to discovery in this acclaimed series. Note: There is no August lecture.

The June 14 lecture will be "Probing Long-term Temperature Change in the Southern Ocean" with Sarah Gille, Scripps physical oceanographer.

The ocean is a critical component of the earth’s climate system, storing and transferring heat in ways that are not yet completely understood. Join Scripps Oceanography physical oceanographer Sarah Gille as she describes how she and her colleagues are assessing temperature change in the ocean, exploring mechanisms that might be responsible for observed changes and grappling with the implications of ocean warming for global climate change.

Date & Time: June 14, 6:30 p.m.

Decadal-Timescale Estuarine Geomorphic Change Under Future Scenarios of Climate and Sediment Supply

_T14b — Sun, 13 Jun 2010 05:01:07 +0000

Future estuarine geomorphic change, in response to climate change, sea-level rise, and watershed sediment supply, may govern ecological function, navigation, and water quality. We estimated geomorphic changes in Suisun Bay, CA, under four scenarios using a tidal-timescale hydrodynamic/sediment transport model. Computational expense and data needs were reduced using the morphological hydrograph concept and the morphological acceleration factor. The four scenarios included (1) present-day conditions; (2) sea-level rise and freshwater flow changes of 2030; (3) sea-level rise and decreased watershed sediment supply of 2030; and (4) sea-level rise, freshwater flow changes, and decreased watershed sediment supply of 2030. Sea-level rise increased water levels thereby reducing wave-induced bottom shear stress and sediment redistribution during the wind-wave season. Decreased watershed sediment supply reduced net deposition within the estuary, while minor changes in freshwater flow timing and magnitude induced the smallest overall effect. In all future scenarios, net deposition in the entire estuary and in the shallowest areas did not keep pace with sea-level rise, suggesting that intertidal and wetland areas may struggle to maintain elevation. Tidal-timescale simulations using future conditions were also used to infer changes in optical depth: though sea-level rise acts to decrease mean light irradiance, decreased suspended-sediment concentrations increase irradiance, yielding small changes in optical depth. The modeling results also assisted with the development of a dimensionless estuarine geomorphic number representing the ratio of potential sediment import forces to sediment export forces; we found the number to be linearly related to relative geomorphic change in Suisun Bay. The methods implemented here are widely applicable to evaluating future scenarios of estuarine change over decadal timescales. ... ...
