Organized and quality-controlled CalCOFI data for CTD casts and bottle measurements from CalCOFI stations between La Jolla, California to Point Conception between 1984-2019

Abstract

In this dataset, we analyzed daytime casts (09:00-16:00) of both discrete bottle data and continuous CTD casts from CalCOFI stations restricted to an area from La Jolla, California to Point Conception and 215 km maximum offshore. This dataset has combined bottle and CTD casts to represent the date range 1984-2019. We used the oxygen and irradiance measurements to determine the visual luminoxyscape for each of the larval species. This range was bounded by the oxygen (partial pressure) where the pO2 would permit 50% minimum retinal function (V50; 13, 7.2, 10.2, and 6.8 kPa for larvae of 'Doryteuthis opalescens', 'Octopus bimaculatus', 'Metacarcinus gracilis', and 'Pleuroncodes planipes', respectively), and where there is sufficient irradiance for a visual response (0.0311 µmol photons m-2 s-1) for each species. Additionally, oxygen limits for metabolism were used to determine the depth of occurrence of the Pcrit (the oxygen below which the animal cannot maintain a constant metabolic rate). The depths of occurrence for metabolic limits were determined for larvae of 'D. opalescens' and 'O. bimaculatus'.
