Data indicating which stations are the 2018 (and maybe later) expansion stations

Description

A dataset containing details of the stations for the 2018 IPHC survey; one set was deployed at each usual station, but an expanded grid (more stations) was used this year, and the expansion stations need to be kept track of when comparing spatially-averaged catch rates to previous years. 2019 onwards may also use the expanded grids. Effective skate number, avgDepth and usability will come from the GFbio query (unlike, say, setData2013, for which the set details could not go into GFbio). For 2020 the IPHC provided an expansion column, which didn't quite match these – see data-raw/iphc-2020-data.Rmd or .pdf for calculations. In particular, to explain why station 2343 is redefined here as being standard.

Usage

setDataExpansion

Format

A tibble:

station

station name (character because early years used alphanumeric and need to be able to combine years later)

lat

latitude of station

lon

longitude of station

standard

whether or not (Y/N) the station is a standard one or an expansions station

rca

whether or not (Y/N) the station is within a Rockfish Conservation Area

mpa

whether or not (Y/N) the station is within a Marine Protected Area

mpa_name

name of the Marine Protected Area that the station is within, if applicable (else is character NA)

Source

Originally from file IPHC_Stations_All.csv from Dana Haggarty (later updated as IPHC_FISS_All_Stn_GFBio.csv to include the seven stations originally missing but that were in GFbio), with details and further tidying done here in data-raw/IPHC-stations-expanded.R.
