2008 Ocean Sciences Meeting -- media advisory 2

Press conference schedule, dial in for press conferences, press room information

1. Press Conference Schedule

The following schedule of press conferences is subject to change, before or during the Ocean Sciences Meeting. Press conferences may be added or dropped, their titles and emphases may change, and participants may change. All updates to this schedule will be announced in the Press Room (W307D, West Building, Orange County Convention Center). Press conferences take place in the Press Room. The times listed below are Eastern Standard Time.

Human impacts on coastal ecosystems
Monday, 3 March
1200

Ecosystems that encompass watersheds and their coastal receiving waters are under particular threat from human impact. New findings show how nutrient inputs from rivers into the most productive areas of the global ocean, called marginal seas, make those seas vulnerable to damming, land-use practices, and increasing world population. Other research indicates that the long-term sustainability of deltas is generally compromised more by large-scale engineering projects—which result in shoreline erosion, threatened mangroves and wetlands, and increased salinization of cultivated land—than by sea-level rise. New studies of bays offer insights about phosphorus ranging from why Florida Bay has seagrass-killing algal blooms despite extremely low phosphorus from the Everglades to evidence from the Chesapeake Bay watershed that 90 percent of the human-related phosphorus inputs are retained in the watershed.

Ocean Acidification: Causes and Impacts on Biogeochemical Processes, Biota and Climate
Monday, 3 March
1600

As the world’s oceans become more acidic, many calcifying marine organisms will be negatively impacted, which could lead to cascading effects throughout marine food webs. Increasing amounts of dissolved anthropogenic carbon dioxide (CO2) in oceans intensifies acidity and reduces carbonate-ion levels. A new look at field measurements from Bermuda’s coral reefs, where models have predicted early effects from ocean acidification, reveal a seasonal correlation between carbonate ion levels and how fast those reefs calcify. Other laboratory work mimicking future ocean-acidification conditions finds a marked decline in phytoplankton growth when pH decreases by more than 0.25 units. By using models in other studies, research teams are anticipating when detectable global declines in calcification by marine organisms will occur and exploring how much acidification would result from specific levels of human-generated CO2 emissions.

Diving deeper into coral-reef health
Tuesday, 4 March
1000

Coral reefs face threats from increasing seawater temperatures, ocean acidification, and alterations of seawater organic carbon chemistry. Temperature increases can result in an unhealthy, often fatal condition called bleaching. Newly presented findings indicate that coral recovery from bleaching depends on coral’s ability to utilize zooplankton as a primary food source to support tissue healing and growth and to regain photosynthetic capabilities necessary for calcification. Another study shows that, under ocean acidification scenarios caused by increasing atmospheric carbon dioxide, coral reef community structure could change dramatically, portending future reef ecosystems markedly different from current ones. Other research looks at consequences of altered chemical conditions of waters surrounding coral reefs as a result of coastal landscapes rapidly changing from increasing human populations. Findings discussed here suggest that variations in the water column pool of dissolved organic matter may alter bacterial communities associated with corals and adversely affect coral health.

River plumes sequester carbon in tropical oceans
Tuesday, 4 March
1600

Independent teams of researchers studying the basins and plumes of major tropical rivers find significant and surprising drawdown of carbon dioxide (CO2) from the atmosphere into the ocean by microorganisms in large plumes that can cover an ocean area more than twice the size of Texas. Carbon sequestration comes as a surprise because, in warm tropical oceans, CO2 usually outgasses. Researchers find that the specific organisms responsible for carbon drawdown may differ between the various river plumes, but that these organisms are regulated by the biogeochemistry of the river and are sensitive to human activity. New evidence shows that the land and water use in the drainage basin of great rivers such as the Amazon and the Mekong control river biogeochemistry and that activities such as dam construction and changing agricultural practices alter conditions at various scales. A team studying the Mississippi and Orinoco Rivers, finds much greater productivity, CO2 drawdown, and carbon-uptake gene expression near the mouth of the Mississippi than in the Orinoco, possibly due to anthropogenic nutrient loading in the Mississippi. Other scientists studying the Amazon plume find that its rates of carbon drawdown can almost equal the outgassing of CO2 from the rest of the tropical North Atlantic.

Aquaculture’s impact on water quality and sediments
Thursday, 6 March
1000

Worldwide, fish supply from capture fisheries has been flat or in decline for the last twenty years. Fish farming, or aquaculture, is increasingly meeting the growing demand for protein in human nutrition. The 'burning issues' surrounding aquaculture concern the effects of the farms on the environment—for instance, on water quality and sediments. Panelists will discuss new findings regarding the impact of waste from marine farms, how bottom-living organisms respond, and how habitats can recover.

Session 045

Iron overboard! Profound idea or shallow scheme?
Thursday, 6 March
1300

Island systems in the Southern Ocean naturally release iron on a large scale and may act as a model to examine hotly debated iron-fertilization proposals. In such proposals, adding iron to ocean zones where a lack of the element limits plant growth helps stimulate uptake of carbon dioxide by marine plants. Proponents of the approach argue that large-scale manipulation of such areas as the Southern Ocean can help alleviate man's present excessive release of the greenhouse gas carbon dioxide. However, an important unresolved question is: Will this large-scale geo-engineering really lead to efficient transport of carbon to the deep ocean, where it should be locked away for hundreds of years, or will that carbon be rapidly recycled in the upper ocean and released back to the atmosphere? Recent research shows the efficiency of the carbon transfer to deep waters in one of these Southern Ocean island systems appears much less than assumed in the geo-engineering plans.
