Multispecies Small-Mesh Bottom Trawl (MSSM) Survey Grid
Description
A 3x3 km grid for the Multispecies Small-Mesh Bottom Trawl Survey (MSSM; formerly
known as 'shrimp survey'). This grid covers WCVI Shrimp Survey Areas 124 and 125.
The year is the last year a grid cell was sampled as of 2023, with
the most consistent resampling (spatially) occurring in grid cells last sampled
between 2009 and 2021.
Usage
mssm_grid
mssm_grid_sf
Format
mssm_grid
A data frame with 3,735 rows and 5 columns:
- survey_abbrev
Survey abbreviation
- longitude, latitude
Longitude and latitude of the centroid of 3x3 km
grid cells
- area
Area of the grid cells, in km^2
- year
The year a grid cell was sampled. A grid cell can have multiple year values
mssm_grid_sf
