Exploratory data analysis and preparation of data for ML model
For SST data preparation three main sources to be used
- MI underway SST data
- ICES data
- NOAA SST data(0.25 × 0.25) and Copernicus SST data (0.05 × 0.05)
Step 1
Analysis and explore the Marine institute SST data
MI underway SST data
Temporal resolution:10sec, surface of the ocean.
For Marine heatwave daily resolution is needed, averaging each day 10sec data to daily data.
Step 2
Use the ICES data to do the gap filling
As underway data is of the surface of ocean(depth=0), therefore only data taken at depth=0 is considered
- Bottle low resolution data
- XBT data
- High resolution data
- Pump data (Temperature data is all blank at depth=0), hence eliminated
- Ocean Surface data
Jupyter code file name: ices_datamerge
All the above sources are merged(excluding pump data)
Step 2.1
After this MI and ICES data are merged(merged_data\icesmi_merged_data.csv)
Jupyter code file name: icesmi_merge
Step 3
Use NOAA or Copernicus data to do the gap filling based on the grid we want 0.25 × 0.25 or 0.05 × 0.05
