BCO-DMO is preparing to move to a new data access system that provides more functionality and features. This system, called ERDDAP, is free and open source with a strong and growing user community. Currently, we are providing the following data access and download capabilities for datasets as we work through our legacy data holdings. These capabilities will soon be available for all data at BCO-DMO:Data Access
- - view the data in an HTML table
- - filter the data before viewing or downloading in a variety of formats
- - download the data with comma-separated values (Excel-ready)
- - download the data with tab-separated values (Excel-ready)
- - download the data as GeoJSON. Try it out at geojson.io
- - download the data as a valid MATLAB file
- - download the data in NetCDF format
- - download the data in Ocean Data View format

Environmental temperature data collected at Cerro Mundo Bay, San Cristobal, Galapagos from 2022-2023 (Galapagos 2021 project)
Abstract:
Increased standing macroalgal biomass in upwelling zones is generally assumed to be the result of higher nutrient flux due to upwelled waters, However, other factors can strongly impact macroalgal communities. For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence macroalgal biomass and productivity, respectively. Although there is a fair number of studies looking at the interactive effects of herbivores and nutrients in both tropical and temperate regions, there is a lack of studies looking at these effects in tropical or subtropical upwelling regions. The purpose of this study was to measure the effects that herbivores, temperature, and nutrient availability have on standing macroalgal biomass. We manipulated nutrient availability and herbivory in six field experiments during contrasting productivity and thermal regimes (cool-upwelling and warm, non-upwelling season) on a subtidal nearshore rocky reef.
Here, we present a set of temperature (°C) data collected at Cerro Mundo Bay, San Cristobal, Galapagos from September 2022 to February 2023. The environmental temperature was recorded every 15 minutes using a HOBO Water Temperature pro V2 Data Logger (Onset®) attached to the seafloor at a 10 meters depth mark.
