Autumn Leaves (Litterfall) Mercury Pathway Equals Precipitation
USGS research hydrologist Martin Risch said, "Before these studies, we didn't know the extent of litterfall as a mercury pathway in different types of forests across the eastern U.S. Our research found that annual amounts of mercury deposited in autumn litterfall from deciduous forests were equal to or exceeded the annual amounts deposited in precipitation." Most of the mercury that eventually ends up in fish and food webs comes from the air, and much of the mercury in the air comes from human sources such as coal-fired power plants, industrial boilers, cement manufacturing, and incinerators. Forest canopies naturally remove mercury from the air and incorporate the mercury into and onto the leaves and needles of trees.
USGS scientists researched mercury levels in litterfall from forests over a three-year period in 15 eastern U.S. states. When they compared the results to those from a separate study of mercury in precipitation within the Great Lakes region, they found similar geographic patterns for mercury in litterfall and mercury in precipitation: Both types of mercury deposition were generally high in the same areas and low in the same areas. Risch said, "The similar geographic patterns indicate that the same mercury emissions sources affecting mercury levels in precipitation in an area also may affect mercury levels in forests and litterfall in that same area."
Furthermore, USGS said the precipitation study found no improvement in the amount of atmospheric mercury deposited by precipitation in the Great Lakes region over a 7-year period, and found that the amount of precipitation in the region had increased during this time. This precipitation study covers a time period that precedes new regulations by U.S. EPA to reduce mercury emissions in the U.S.

ACRCC Steps Up Monitoring With More Positive eDNA Results
At present, eDNA evidence cannot verify whether live Asian carp are present, whether the DNA may have come from a dead fish, or whether water containing Asian carp DNA may have been transported from other sources, such as bilge water. The monitoring response is designed to intensify resources and use the best available technology to search for live Asian carp in the Lake Calumet area. Eight previous monitoring trips to Lake Calumet since March 2011 have identified 4,500 fish and indicated no Asian carp presence.
John Goss, Director of the White House Council on Environmental Quality (CEQ) said, "Finding three or more consecutive sets of positive eDNA samples in the same area triggers us to use significant resources to try to find a physical specimen. Through the ACRCC's comprehensive Asian carp control strategy, we remain vigilant both in monitoring to keep Asian carp out of the Great Lakes, and also in investigating all possible sources of Asian carp DNA to minimize the human transfer element such as people unknowingly using Asian carp as bait or other activities that could transfer them to the Great Lakes."
Biologists from the U.S. Fish and Wildlife Service, the U.S. Army Corps of Engineers (ACOE) and the Illinois Department of Natural Resources will be on the water with commercial fishermen and biologists from Southern Illinois University and the Illinois Natural History Survey beginning Monday August 1st through Thursday August 4th. The crews will lay various net types throughout the Lake Calumet area, including half-mile long seine nets to sweep large portions of the area. Electrofishing boats will sample fish in shoreline areas and will be used to drive fish towards the nets. Commercial and private vessel traffic will be able to proceed with minimal interference from the monitoring activity. Three separate eDNA samples sets were taken at Lake Calumet between June 15 and July 19 and revealed 11 positives (all Silver carp DNA) out of 328 samples taken.

Businesses Form WOC To Participate In Marine Spatial Planning
According to a release, the recently initiated MSP agenda pursuant to President Obama's National Ocean Policy is moving rapidly, creating a critical opportunity for the ocean business community to actively engage in a coordinated, multi-sectoral manner. In 2010, the Federal government established an interagency National Ocean Council (NOC), and marine spatial plans are to be developed by nine regional planning bodies as early as 2015. The NOC issued a Strategic Action Plan Outline in June 2011 and held a national workshop soon after to prepare government agencies for the task of developing the government's MSP Strategic Action Plan. Unlike the ocean industry community, the environmental community has had a national MSP coalition for several years and is actively involved in the MSP process.
WOC indicates that the ocean business community needs to get equally well organized and integrated into the discussion on MSP. To address this, the WOC brought together leadership companies and associations concerned about access to ocean space and resources in a National Business Forum. The Forum was co-presented by Battelle Memorial Institute with additional sponsorship from the National Ocean Industries Association and Blank Rome.
The business community voiced concerns that opportunities for ocean industries to formally contribute to MSP have not targeted engaging those industries which contribute significantly to the U.S. economy and need to become a more structural part of the US MSP process. To address the lack of formal engagement, industry participants at the Forum emphasized the value and strength in bringing together diverse ocean industry sectors to engage with MSP decision makers in a coordinated manner, and to establish formal avenues for frequent and ongoing information exchange and involvement.
