Abstract: |
A compilation of ocean nutrient (nitrate, phosphate, and silicate concentrations) data at ¼ degree spatial resolution for the entire United States Exclusive Economic Zone. The dataset is derived from the ESRI Ecological Marine Unit (EMU) dataset, which was assembled from non-supervised statistical clustering of over 52 million points from NOAA’s World Ocean Atlas (2013) WoA database, an authoritative 57 year archive of global water column data. This derived dataset is divided into three separate point shapefiles, each representing either nitrate, phosphate, or silicate concentrations (all in units of μmol l-1). Values for nutrient concentrations represent a climatological average. Each shapefile is formatted such that a single point location (i.e., unique associated latitude and longitude) contains a unique column entry for a given depth interval. Depth intervals are variable from 5 m near the surface to 100 m in the deeper regions (> 2000 m) for a total of 102 depth levels. All disclaimers provided by the original dataset authors apply to this derived dataset. For detail on these disclaimers, please refer to the following reference: Sayre, R., J. Dangermond, D.

Process Steps
Process Step 1
Description: |
(1) ESRI Ecological Marine Units data clipped to the boundaries of the United States Exclusive Economic Zone were provided by Keith VanGraafeiland (ESRI). Data were provided in a large point shapefile format with multiple points associated with a single latitude and longitude location. Original attribute fields included those representing depth, unique ecological marine units, nutrients (nitrates, phosphates, silicates), temperature, salinity, dissolved oxygen, among other related fields. (2) Data were re-shaped into a single point shapefile for each nutrient parameter (i.e., nitrates, phosphates, silicates). These shapefiles contain a unique point representing each single latitude and longitude location. Each shapefile contains two unique identifier attributes: FID and QtrDegreeI. QtrDegreeI allows each unique point location to be referenced back to the original ESRI Ecological Marine Units Dataset. Attribute fields for nutrient concentrations at depth were added for each point within the shapefile. These fields were derived from the original dataset and represent nutrient concentrations within each depth interval (e.g., N_001-N_101 wherein N_001 represents nutrient concentrations for waters between 0 and 5 m depth). |
