SBC LTER: BEACH: Talitrid amphipod (Megalorchestia spp.) mesocosm and pitfall trapping for surface activity on spring and neap tides

These data describe the surface activity of talitrid amphipod species (Megalorchestia spp.), and unidentified juveniles, on a spring tide and a neap tide during July and August 2017. The data tables include (1) the mean number and standard deviation of surface active individuals of each species each hour for a 24 hour period on a spring tide and on a neap tide in mesocosms, and (2) the count of each species and unidentified juveniles from pitfall trap samples collected every 2 hours on 4 replicate transects on a spring tide and on a neap tide. This dataset is to support the journal article: Emery, KA, VR Kramer, NK Schooler, KM Michaud, JR Madden, DM Hubbard, RJ Miller, JE Dugan. 2021.
