    Assessing public support for commercial fishing in the ocean twilight zone
    (Woods Hole Oceanographic Institution, 2024-04-11) Weir, Michael J. ; Lozinsky, May ; Jin, Di
    Biomass in the mesopelagic or “twilight” zone (OTZ) of the ocean is estimated to be 10-100 times that of current annual capture fishery production and plays a fundamental role in regulating global climate via both biological and physical processes. Recently, OTZ fisheries have gained commercial attention to support aquaculture feed production. However, scientific uncertainty remains about the OTZ’s link to carbon cycling processes making it difficult to craft a comprehensive policy to regulate human intervention and mitigate negative consequences. We distribute a choice experiment among U.S. residents to estimate the potential social benefit associated with expanding OTZ fisheries and whether ocean literate individuals experience a different degree of benefits. The files included in this repository will facilitate replication of the choice modeling and summary statistics presented in the manuscript.

    Testing for a shift in a species boundary
    ( 2013-12-09) Solow, Andrew R. ; Beet, Andrew R. ; Roll, Uri ; Stone, Lewi
    One predicted impact of climate change is a poleward shift in the boundaries of species ranges. Existing methods for identifying such a boundary shift based on changes in the observed pattern of occupancy within a grid of cells are sensitive to changes in the overall rate of sightings and their latitudinal distribution that are unconnected to a boundary shift. A formal test for a boundary shift is described that allows for such changes. The test is applied to detect northward shifts in the northern boundary of the Essex skipper butterfly and the European goldfinch in Great Britain. A shift is detected in the latter case but not in the former. Results from a simulation study are presented showing that the test performs well.
