Microplastics area and count data for Scotland's Marine Assessment 2020

The column headings in the Data are:

YEAR
Actual Sampling year
Season
seasons run from Oct in one year to end January in following year - exceptions noted in text
Cruise
Letter refers to ship: S=MRV Scotia, A= MRV alba na Mara, SJM=Sir John Murray (SEPA) eg 0120S is the first cruise of 2020 on the MRV Scotia
Region
Scottish Marine or Offshore Region
Field_ID
Descriptive name of towing site
TOW_ID
made up of cruise number and tow number for the cruise
DATE_Deploy
Date of deployment dd/mm/yyyy
TIME_Deploy
Time of deployment hh:mm
decLat_Deploy
Decimal Latitude at deployment (WGS84)
decLong_Deploy
Decimal Longitude at deployment (WGS84)
DATE_Retrieve
Date of sampler retrieval dd/mm/yyyy
TIME_Retrieve
Time of sampler retrieval hh:mm
decLat_Retrieve
Decimal latitude at retrieval (WGS84)
decLong_Retrieve
Decimal longitude at retrieval (WGS84)
FLOW_METER_READING_deploy
The revolution count of flow meter at time of deployment (used for calculating tow length)
FLOW_METER_READING_retrieve
The revolution count of flow meter at time of retrieval (used for calculating tow length)
Tow_length (m)
calculated by subtracting deploy from retrieve and multiplying by 0.3 (1 revolution of flow meter = 0.3m)
