SYNOPSIS

  • Current research has used remote sensing products to study oceanic relationships and processes, but is mixed on the relationship between salinity and chlorophyll-a.
  • The study aims to better understand the relationship between
    chlorophyll-a and salinity at coastal watersheds around the
    US using remote sensing products.

Research Questions & Research Objectives
  • Purpose: Investigate the relationship between chlorophyll-a, sea surface salinity, and El Niño-Southern Oscillation (ENSO).

  • Temporal relationship: The relationship changes monthly by season or yearly by ENSO strength.

  • Data Visualization: Create an ArcGIS StoryMaps to summarize the study and importance of research using satellite imagery.

Research Methods
  • NASA Satellite Imagery: OISSS in PO.DAAC & MODIS OB.DAAC

  • Observe Relationship at Different Latitudes: Mississippi River, San Joaquin River, Columbia River.

  • Temporal: Analyze monthly-averages of salinity and chlorophyll-a range from 2012-2022.

  • ArcGIS Pro Tools: Analysis and mapping tools.

  • Excel: Analyze and create graphs of descriptive statistics.

Research Deliverables and Products
  • Inconclusive temporal averages alludes to the possibility that the two variables do not correlate or may correlate spatially rather than temporally.

  • Sea surface salinity and chlorophyll-a inhabit an incredibly dynamic environment which can make analyzing their relationship difficult.

  • Further research into how other oceanic processes may affect the sea surface salinity and chlorophyll-a.
