Dataset: 2023 Bottom Temperature Data

We used the American lobster (Homarus americanus) in the Gulf of Maine as a model system to define thermal tolerance in larvae and establish mechanistic linkages between thermal tolerance of the individual larva and the patterns of settlement in the field. We assessed and compared the thermal tolerances of larvae in the laboratory and to link to patterns in the field we measured larval settlement as a function of depth (and therefore temperatures) and deployed caged larvae at different depths (and therefore temperatures). This dataset reports the bottom temperature data from temperature loggers attached to larval settlement collectors placed on the bottom from early June to late September in 2023. Collectors were deployed in coastal waters in the vicinity of Boothbay Harbor, Maine, USA at depths ranging from 7 to 77 meters. Bigelow Laboratory for Ocean Sciences were the base for field operations which were led by Eric Annis and Douglas Rasher.
