Indiana Bat Project data

Richard A Erickson
Our model is a full-annual-cycle population model {hostetler2015full} that tracks groups of bat surviving through four seasons: breeding season/summer, fall migration, non-breeding/winter, and spring migration. Our state variables are groups of bats that use a specific maternity colony/breeding site and hibernaculum/non-breeding site. Bats are also accounted for by life stages (juveniles/first-year breeders versus adults) and seasonal habitats (breeding versus non-breeding) during each year, This leads to four states variable (here depicted in vector notation): the...

Nearshore waves in southern California: hindcast, and modeled historical and 21st-century projected time series

Christie A. Hegermiller, Li H. Erikson & Patrick L. Barnard
As part of the Coastal Storm Modeling System (CoSMoS), time series of hindcast, historical, and 21st-century nearshore wave parameters (wave height, period, and direction) were simulated for the southern California coast from Point Conception to the Mexican border. The hindcast (1980-2010) time series represents reanalysis-forced offshore waves propagated to the nearshore, whereas the historical (1976-2005) and 21st-century (2012-2100) time series represent global climate model-forced offshore waves propagated to the nearshore. Changes in deep-water wave conditions...
