Composition and abundance of macrophyte wrack at six Santa Barbara beaches quantified during surveys conducted from 2015-2017.
We quantified composition and abundance of macrophyte wrack of the six study beaches during each survey from 2015-2017. Wrack composition and cover were recorded for each of six shore-normal transects of variable length that extended from the lower edge of terrestrial vegetation or the bluff to the lowest intertidal level exposed by swash at each location. The transects were randomly assigned to locations within the first 100 m of shoreline from the access point using a random number table and a distance measuring wheel. We used a line-intercept method along each transect tape to quantify wrack cover. The presence and extent (length, depth) of each type of macrophyte, driftwood, carrion, tar, trash and any other beach-cast wrack was recorded along each transect tape, yielding total wrack cover by wrack type for each transect. Data are reported as m2/m of shoreline.
- joined site coordinates to the data using Site Name as the key;
- converted Date field to yyyy-mm-dd format;
- renamed original 'Type' column to 'Type_Code' and added the definition to new column 'Type';
- replaced commas with semi-colons in the Notes column;
- removed commas from the Type column.
