Basemap functions Main functions to plot maps and transform data to correct projection
basemap()	Create a ggplot2 basemap for plotting variables
add_land()	Add a land layer on basemaps
transform_coord()	Transform spatial coordinates to another projection
qmap()	Quick map
Add charts on maps Functions to add charts on maps. Under development.
waffle_chart()	Plot waffle charts
Create oceanographic plots Functions and datasets to create temperature-salinity and section plots.
ts_plot()	Temperature-salinity (T-S) plot from a data frame using ggplot2
section_plot()	Make an oceanographic section plot from an x-y-z data frame
interpolate_section()	Interpolate x-y-z data for oceanographic section plots
define_water_type()	Define water type based on temperature and salinity
kongsfjord_watermasses	Water mass definitions for Kongsfjorden
rijpfjord_watermasses	Water mass definitions for Rijpfjorden
Other functions Functions that do other things
dist2land()	Calculate the closest distance to land for given coordinates
interpolate_spatial()	Interpolate a spatial surface from observations
plot(<spatInt>)	Plot an interpolated map
LS()	Convert line sizes measured as points to ggplot line sizes
FS()	Convert font sizes measured as points to ggplot font sizes
Example datasets Datasets used as examples for package functions
chlorophyll	Chlorophyll-a recordings in Kongsfjorden
kongsfjord_moorings	Location of recorded moorings in Kongsfjorden
npi_stations	Location of NPI's permanent marine biological monitoring stations
meiofauna	Pan-Arctic meiofauna data from Bluhm et al. 2018
zooplankton	Zooplankton data
ctd_kongsfjord	Example CTD data for Kongsfjorden
ctd_rijpfjord	Example CTD data for Rijpfjorden
Internal basemap functions Internal functions dealing with data and graphics for basemap. These functions are run on the background and only needed if you modify your maps beyond the options offered by PlotSvalbard.
auto_limits()	Automatic limits for basemap
basemap_data()	Create basemapData object for basemap plotting
basemap_limits()	Define limits for a basemap
clip_bathymetry()	Clip a bathymetry shapefile to fit a basemap
clip_current()	Clip ocean current data frame to fit a basemap
clip_shapefile()	Clip a shape file (SpatialPolygon) using a bounding area
deg_grid()	Decimal degree grid from UTM projected spatial objects
deg_grid_polar()	Decimal degree grid from polar stereographic spatial objects
map_cmd()	Return map elements for basemap
map_projection()	Get the projection for a map type
map_type()	Get information for a map type
theme_map()	A ggplot2 theme for maps
Shapefiles Shapefiles used by the package. These shapefiles are automatically used by the basemap function. Introducing new shapefiles is only required if you want to improve the resolution or use PlotSvalbard to make maps outside the Svalbard region.
arctic_bathy	SpatialPolygonsDataFrame containing pan-Arctic bathymetry
arctic	SpatialPolygonsDataFrame containing land shapes for pan-Arctic map with a cutpoint at 40 degrees latitude.
barents_bathy	SpatialPolygonsDataFrame containing bathymetry for the Barents Sea
barents_currents	Data frame containing Atlantic and Arctic ocean currents for the Barents Sea
barents.ld	SpatialPolygonsDataFrame containing land shapes for the Barents Sea region.
kong.cr	SpatialPolygonsDataFrame containing clip boundaries for Kongsfjorden
mosj.cr	SpatialPolygonsDataFrame containing clip boundaries for the Environmental Monitoring on Svalbard and Jan Mayen transect
svalbard_bathy	SpatialPolygonsDataFrame containing detailed bathymetry for Svalbard region
svalbard.gl	SpatialPolygonsDataFrame containing glacier boundaries on Svalbard. The tidal-glacier fronts for Kongsfjorden are from July 2017, while the rest vary between 2005 and 2017.
svalbard.ld	SpatialPolygonsDataFrame containing land shapes for Svalbard
