PacMARS: Integrated Chlorophyll (0-100 m, mg m-2), Summer, Gridded

Summary

This data set contains the integrated chlorophyll concentration (milligrams per square meter (mg/m2)) in the upper 100 meters or total water column for depths shallower than 100 meters from the Pacific Marine Arctic Regional Synthesis (PacMARS) Chlorophyll compilation v6 to a grid of 0.5 degrees. Measurements were taken on latitude from 63.5 to 78 degrees north and 2 degrees and longitude from -180 to -135 degrees east. There are three columns in the file: longitude, latitude, and integrated chlorophyll (milligrams per square meter (mg/m2)). Missing values are denoted as NaN. These data were collected in July through September.

Note: sources for the data are listed in the documentation link below, and more completely available in the companion dataset.
