E-mail: ktl@postech.ac.kr Abstract The relative abundance of nitrate (N) over phosphorus (P) has increased over the period since 1980 in the marginal seas bordering the northwestern Pacific Ocean, located downstream of the populated and industrialized Asian continent. The increase in N availability within the study area was mainly driven by increasing N concentrations and was most likely due to deposition of pollutant nitrogen from atmospheric sources. Atmospheric nitrogen deposition had a high temporal correlation with N availability in the study area (r = 0.74 to 0.88), except in selected areas wherein riverine nitrogen load may be of equal importance. The increase in N availability caused by atmospheric deposition and riverine input has switched extensive parts of the study area from being N-limited to P-limited. "

Project Kaisei - Capturing the Plastic Vortex - 0 views

  •  
    "Project Kaisei is a non-profit organization based in San Francisco and Hong Kong, established to increase the understanding and the scale of marine debris, its impact on our ocean environment, and how we can introduce solutions for both prevention and clean-up. \n\nOur main focus is on the North Pacific Gyre, which constitutes a large accumulation of debris in one of the largest and most remote ecosystems on the planet. To accomplish these objectives, Project Kaisei is serving as a catalyst to bring together public and private collaborators to design, test and implement break-throughs in science, prevention and remediation.\n\nKaisei means "Ocean Planet" in Japanese, and is the name of the iconic tall ship that was one of the two research vessels in the August expedition."

Unicellular Cyanobacterial Distributions Broaden the Oceanic N2 Fixation Domain - 0 views

  •  
    "Nitrogen (N2)-fixing microorganisms (diazotrophs) are an important source of biologically available fixed N in terrestrial and aquatic ecosystems and control the productivity of oligotrophic ocean ecosystems. We found that two major groups of unicellular N2-fixing cyanobacteria (UCYN) have distinct spatial distributions that differ from those of Trichodesmium, the N2-fixing cyanobacterium previously considered to be the most important contributor to open-ocean N2 fixation. The distributions and activity of the two UCYN groups were separated as a function of depth, temperature, and water column density structure along an 8000-kilometer transect in the South Pacific Ocean. UCYN group A can be found at high abundances at substantially higher latitudes and deeper in subsurface ocean waters than Trichodesmium. These findings have implications for the geographic extent and magnitude of basin-scale oceanic N2 fixation rates. "

    Webcast: 'We Sea Change,' a Climate Change Education Video 0 What is climate change, and how is it affecting coastal Carolina? That is the question that a group of teens from Isaac Bear Early College High School set out to answer for their Third National Student Summit on the Ocean & Coasts project. Representing the North Carolina Aquarium at Fort Fisher, four teens spent months researching climate change issues such as salt water intrusion in rivers, changes to barrier islands, disappearing beaches, and habitat loss in longleaf pine forests in the Wilmington, N.C., region. The students presented a video documenting this research during the National Student Summit on February 15, 2011 at the Smithsonian's National Museum of Natural History. After the Summit, the team broadened the project's scope to include climate change education through the production of a second video. This film, We Sea Change, aims to give their local community in Wilmington an understanding of climate change, impacts on the coastal Carolina region, and how people can be part of the climate change solution. We Sea Change will be broadcast live to the Ocean Portal from the North Carolina Aquarium at Fort Fisher on Wednesday, September 28, 2011 at 7pm. There will be a panel discussion on climate change immediately following the 7pm screening. Meet the team! The Cape Fear Beach Bears: Sandy Paws for a Cause team members include students Jessica Lama, Keela Sweeney, Evan Lucas, and Dustin Chambers. They have conducted research and produced their videos under the guidance of teachers Bryan Bishop from Isaac Bear Early College High School and Megan Ennes from the North Carolina Aquarium at Fort Fisher.

Fam Camp - California State Parks Foundation - 0 views

  •  
    California State Parks Foundation program\n"Currently, State Parks operates 14 mobile FamCamp® equipment trailers at selected state park sites throughout California. Each year approximately 1,600 children and family members have the opportunity to participate in a FamCamp® trip - an experience that strengthens family bonds and builds a greater environmental ethic among urban families. Since 2000, the Foundation has raised more than $292,000 for this program. In 2007, we are committed to building strategic public-private partnerships that enable low-income families to participate in the FamCamp® program and experience California's magnificent state parks."
