Observations of the 1992 U.S. Pelagic Pair Trawl Fishery in the Northwest Atlantic [PDF]

open access: yes, 1994
Pelagic pair trawling for tuna, Thunnus spp., and swordfish, Xiphias gladius, was introduced in U.S. Northwest Atlantic waters in 1991. During autumn (October-November) of 1992 under the authority oft he Federal Atlantic Swordfish Regulations, the ...

CO Spillover‐Induced Directed C─C Coupling for CO2 Electroreduction to Multicarbon Products

open access: yesAdvanced Energy Materials, EarlyView.
Efficient CO2 electroreduction to C2+ is achieved by engineering Cu@Ag interfaces, which enhance interfacial CO spillover from Ag to Cu, enrich *CO coverage, and accelerate C─C coupling. A quantitative relationship between CO spillover rate and C2+ activity is also established, defining spillover as a measurable descriptor and advancing rational ...

Trawling for evidence: An ecosystem-based multi-method trawling impact assessment

open access: yesFisheries Research, 2023
© 2023 The Authors. Robust methods for assessing fisheries impacts are required to support evidence-based management and contribute to the assessment of protected areas. Under marine policies, such as the Marine Strategy Framework Directive, effective management requires an understanding of impacts at the fisheries scale and needs to account for the ...

A nursery site of the Alaska skate (Bathyraja parmifera) in the eastern Bering Sea [PDF]

open access: yes, 2008
A nursery site for the Alaska skate (Bathyraja parmifera) was sampled seasonally from June 2004 to July 2005. At the small nursery site (~2 km2), located in a highly productive area near the shelf-slope interface at the head of Bering Canyon in the ...

Temperature and Farm Labor in Nigeria

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Impact of the commercial fishery on the population of bait shrimp (Penaeus spp.) in Biscayne Bay, 1986 [PDF]

open access: yes, 2003
Monthly population size of bait shrimp in the Bay was estimated from December 1984 to July 1985. Growth rates for male and female P. duorarum showed that pink shrimp exhibit a mean residence time in the nursery area (Biscayne Bay) of approximately 21 ...

New findings and a new species of the genus Ammothea (Pycnogonida, Ammotheidae), with an updated identification key to all Antarctic and sub-Antarctic species [PDF]

open access: yes, 2014
Specimens of the pycnogonid genus Ammothea collected during the Polarstern cruise XXIII/8 (23 November 2006–30 January 2007) were studied. Nine species were recognized in this collection: Ammothea bentartica, A. bicorniculata, A.

Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...

Use of stereo camera systems for assessment of rockfish abundance in untrawlable areas and for recording pollock behavior during midwater trawls [PDF]

open access: yes, 2010
We describe the application of two types of stereo camera systems in fisheries research, including the design, calibration, analysis techniques, and precision of the data obtained with these systems. The first is a stereo video system deployed by using
