- Oceanographic Analysis Techniques Matching:
- GIS (Geographic Information Systems) $\to$ III) Mapping and monitoring fisheries habitats and resources: Spatial database technology used to overlay bathymetry, chlorophyll, and vessel GPS tracks for habitat mapping.
- Remote Sensing $\to$ IV) Utilizing satellite imagery for oceanographic research: Derives sea surface temperature (SST) and ocean color (chlorophyll-a) from orbital satellite sensors.
- Synoptic Analysis $\to$ I) Examination of large-scale ocean features and phenomena: Simultaneous observation of broad meteorological and oceanographic conditions over vast spatial scales.
- Short-term productivity changes $\to$ II) Study of rapid fluctuations in ocean productivity: Investigates ephemeral bloom events, upwelling pulses, and tidal productivity dynamics.
- Matching Summary:
- Correct Option: Option 4.
