Abstract
These datasets were used to assess the fresh pulse observed in the New York Bight (NYB) in 2024 and its ecological impacts. These datasets, assessed in the NYB, include the annual cumulative cold pool volume; the annual cumulative volume of freshwater; the aragonite saturation state by year, season and depth class; the density of Calanus finmarchicus copepods by year, season and depth class; body condition index values for humpback whales by year; and estimates of the number and residence time of humpback whales from photo-identification. Detailed methods for each of these datasets is available in the manuscript published in Scientific Reports (DOI : https://doi.org/10.1038/s41598-026-57921-4).

Description of the data and file structure
Aragonite saturation state and copepod data were obtained during research cruises in the New York Bight, while cold pool volume and the volume of freshwater were calculated from Doppio, a Regional Ocean Modeling System (ROMS)-based model of the Mid-Atlantic Bight. Humpback whale photo-ID and body condition were obtained from small boat survey efforts in the New York Bight. Methods as described in Thorne et al. 2026
