This is a draft version of a 4 dimensional grid of estimates of (lon (x360), lat (x180), depth (x33), time (x20)) anthropogenic carbon content in the ocean (in micromoles of anthropogenic carbon per kg of seawater). These estimates span from the preindustrial era (in which the estimates are small negative numbers in 1750 c.e.) to projections through 2500 c.e. that are derived assuming constant ocean circulation and atmospheric CO2 growth trajectories according to SSPs (and a simple linear fit). Pathway1 contains information from preindustrial through late 2010s based on historical atmospheric CO2. All pathways contain projections from 2020 through 2500 c,.e..
