Region 10 2018 sampling - USEPA/SuRGE GitHub Wiki

Region 10 sampled nine reservoirs in 2018 using methods very similar to that of SuRGE. Full details of the sampling campaign can be found in the QAPP at SharePoint (...\SuRGE Survey of Reservoir Greenhouse gas Emissions - Documents\projectDocuments\QAPP, SOPs, manuals, HASP\QAPP for an assessment of methane emissions from Region 10 reservoirs.docx).

The lake names used in 2018 map to SuRGE lake_id values per the table below. Water chemistry was collected from a site in the open water portion of the reservoir and a site near the main tributary inflow. Chlorophyll was collected from the same two sites plus additional sites at a few reservoirs. Lets read in all chlorophyll data. These will be useful for calibrating sonde based chlorophyll measurements. To be consistent with the SuRGE protocol, lets only read chemistry data from the open water site (see below for site_id). Samples were only collected from the shallow depth. Sample depth is recorded in the cross id field in the nutrient data spreadsheet and a value of 0.1 means a sample depth of 0.1m. This should be converted to sample_depth == shallow in the R data object.
