In Franvgls/NeAtlIBTS: R Library for the Northeastern Atlantic & NS IBTS Surveys

library(NeAtlIBTS.R)

Plots of gear behaviour from the NorthEastern Atlantic IBTS

• Graphs available from the HH DATRAS files
• This package produces figures of the different parameters of the gear behaviour in relation to Depth and between them.
• Data can be downloaded directly from DATRAS making use of the icesDATRAS library,
• Or taken from the working directory, where they should be loaded in advance with the DATRAS HH format
• Default colors are dark blue for the depth, and steelblue for the shallower depths.

Warp vs Depth graphs

par(mfrow=c(1,2))
gearPlotHH.wrpdp("SWC-IBTS",c(2011:2016),1,col1="darkblue")
gearPlotHH.wrpdp("SWC-IBTS",c(2011:2016),1,col1="darkblue",pF=F)

• pF option hides the points and leaves the curves to remark gear behaviour
• You can download the data for the years selected using the function getHHdata.ts

ieigfs<-getHHdata.ts(Survey="IE-IGFS",years=c(2011:2016),quarter=4)

Door spread vs depth graphs

• Once downloaded the data we can produce plots and format them without downloading again

par(mfrow=c(1,2))
gearPlotHH.dodp(ieigfs,years=c(2011:2016),quarter=4,getICES = FALSE)
gearPlotHH.dodp(ieigfs,c(2011:2016),4,pF=F,getICES=F)

Wing spread vs depth graphs

par(mfrow=c(1,2))
gearPlotHH.wgdp("EVHOE",c(2011:2016),4,.3)
gearPlotHH.wgdp("EVHOE",c(2011:2016),4,.4,pF=F)

Net opening (Vertical) vs depth graphs

par(mfrow=c(1,2))
gearPlotHH.nodp("SP-PORC",c(2011:2016),3,.3)
gearPlotHH.nodp("SP-PORC",c(2011:2016),3,.4,pF=F)

Door spread vs Wing spread graphs

par(mfrow=c(1,2))
gearPlotHH.wgdo("SP-ARSA",c(2014:2016),1,col1="darkblue",col2="steelblue2")
gearPlotHH.wgdo("SP-ARSA",c(2014:2016),1,col1="darkblue",col2="steelblue2",pF=F)
