Temperature Data | MARINe

Seawater temperature

Intertidal temperature data have been collected at MARINe sites since 1999. Intertidal temperature data were continuously recorded, typically at 15 or 30 minute intervals. Three different data logger models (all from Onset Computer Corporation) have been used over time and across sites, due to changes in logger technology: StowAway TidbiT TBI32-05+37HOBO pendant UA-002-64, and HOBO UTBI-001 TidbiT v2. Loggers at most sites were housed in stainless steel wire mesh cages and bolted to the substrate. At some Washington sites, loggers were either encased in epoxy for protection and then bolted and epoxied to the bedrock, or housed in flow-through PVC tubes that were bolted to the substrate. Temperature loggers were installed in the mid-low intertidal zone, in areas that would afford some protection from waves and theft. No attempt was made to standardize factors that could affect temperature during emersion, such as shading, angle of incidence to sun, etc. Therefore, we included temperature data only from periods when loggers were fully submerged and recording seawater temperature.

Robomussel Data

We also have a long-term repository of loggers that have been deployed around the world by the Helmuth lab and their many collaborators since 1999. The database comprises intertidal temperatures relevant to the body temperature of intertidal mussels and barnacles. These modified biomimetic instruments record temperatures that are very similar (within ~2°C) to those of living mussels. Notably, these temperatures are often quite different (14°C or more) from those measured by unmodified loggers, and usually much warmer than air temperatures recorded by weather stations. They therefore provide unique insights in to patterns of physiological thermal stress that are undetectable using more commonly-used methods.

More information on modified mussel biomimics (“robomussels”) can be found at Fitzhenry et al., 2004 and in several other papers published by the Helmuth lab.
