View, Subset and Download Data
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

Microbial enzyme activities: peptidase activities of sediment samples from the RV\Polarstern cruise ARKXXVII/3 in the Central Arctic Ocean and Laptev Sea, Aug-Sept. 2012
Abstract:
This dataset includes peptidase hydrolysis rates from sediments to measure microbial enzyme activities. Links to archived CTD data are also provided. Five substrates linked to a 7-amido-4-methyl coumarin (MCA) fluorophore, one amino acid – leucine – and four oligopeptides – the chymotrypsin substrates alanine-alanine-phenylalanine (AAF) and alanine-alanine-proline-phenylalanine (AAPF), and the trypsin substrates glutamine-alanine-arginine (QAR) and glutamic acid-gylcine-arginine (EGR) – were used to measure exo- and endo-acting peptidase activities, respectively.
