©2026 Biological and Chemical Oceanography Data Management Office.This dataset includes seagrass leaf morphometrics (Thalassia testudinum) from 650 experimental plots distributed across 13 sites in the Western Atlantic. Leaf morphology (average widths) were collected at two timepoints, once at the end of the 2018 summer growing season and again at the end of the 2019 winter season. Leaf width is reported as an average of all leaves across 4-6 harvested seagrass shoots in each experimental plot. Sites include: Bocas del Toro, Panama; Bonaire; Little Cayman, Cay...

Sampling details
50 small seagrass plots (0.25m2, all comprised of one species, Thalassia testudinum) were established at 13 shallow sites in the Western Atlantic. Each plot was assigned to one of ten treatments comprising a factorial manipulation of caging, nutrient supply, and canopy clipping: (1) control (2) partial cage (3) full cage (4) added nutrients (5) added nutrients + partial cage (6) added nutrients + full cage (7) full cage + half canopy clip (8) full cage + full canopy clip (9) full cage + added nutrients + half canopy clip (10) full cage + added nutrients + full canopy clip. Leaf morphometrics (only leaf width) was measured at two time points (once at the end of summer 2018 and again at the end of winter 2019). The dataset reports average leaf width as measured across all leaves from 4-6 harvested seagrass shoots from each plot.
