Characterization of the southeastern U.S. Atlantic mid-shelf and deepwater reef fish fisheries.

Michael P. Enzenauer, Simon J. B. Gulak, Bethany M. Deacy &
Observations of the southeastern U.S. Atlantic mid-shelf and deepwater reef fish fisheries (NC through Florida) began in 2007 (Helies and Jamison, 2013). This work was done through the Gulf & South Atlantic Fisheries Foundation soliciting fishing vessels and captains to participate in voluntary observer coverage. The objective was to characterize catch and discards within the snapper-grouper vertical hook-and-line fishery. This approach, while cooperative and inclusive, introduced spatial and temporal sampling biases and did not collect...

White paper on Gulf of Mexico mercury fate and transport.

, Mark Cohen, Chad Hammerschmidt, William Landing, Darren Rumbold & James Simons
This white paper provides back ground and rationale for the priorities laid out in the Action Plan and summarizes our current understanding of mercury in the Gulf of Mexico ecosystem. In addition, the Action Plan emphasizes the identification of special at-risk consumers who ingest larger than average amounts of Gulf of Mexico fish, especially fish with higher than average mercury concentrations . For this reason, we have structured this white paper starting with mercury exposure...

Multi-bank power supply system for small towed hydrophone arrays.

Emily T. Griffiths, J. Scott Ferguson, & Shannon Rankin
Passive acoustic monitoring is quickly becoming a standard component of shipboard cetacean population surveys. Power supplies on survey vessels are often electronically noisy and result in poor quality recordings. An independent battery-powered voltage supply is regularly necessary for high quality recordings. Here we describe the design of a simple system to provide independent, single-sided 12 V power for a towed hydrophone system, such as the Southwest Fisheries Science Center's (SWFSC) Acoustic Recording System (ARS, Rankin...

Assessment and applications of distributed hydrologic model - Russian-Napa River Basins, CA

Lynn E. Johnson, Chengmin Hsu, Robert Zamora & Robert Cifelli
Application of distributed hydrologic models is motivated by the prospect that higher resolution forcing data, such as gridded precipitation fields, should be matched by equivalent resolution mapping of hydrologic responses for surface runoff, soil moisture and evapotranspiration. Distributed hydrologic models have potential for improving hydrologic forecasting given the capability to represent spatially-varying land characteristics and precipitation that has historically been lumped into watershed average characteristics, provided that the distributed model is forced with accurate inputs...

Mortality records, while included in this report, were obviously not evaluated for SI/NSI status. Subsistence and directed takes (i.e., gray whales taken by Russian natives) are not reported here but are reported in SARs published...

Guidance on fishing vessel risk assessments and accounting for safety at sea in fishery management design.

Debra M. Lambert, Eric M. Thunberg, Ronald Gregory Felthoven & Jennifer M. Lincoln
Commercial fishing is one of the most dangerous occupations in the United States. A number of factors can either positively or negatively influence fishing vessel safety, such as: fishing vessel safety regulations, characteristics of the vessel (e.g., age, condition, and maintenance), human competency, weather conditions, and fishery regulations. Several federal agencies have an obligation and interest in promoting fishing vessel safety. NOAA's National Marine Fisheries Service (NMFS) and the eight Regional Fishery Management Councils (Councils)...
