False.
Some ocean carbon does come from the atmosphere (CO2 dissolves into seawater), but not all. Significant carbon enters the ocean from rivers (weathering and runoff), biological production and decomposition, hydrothermal vents and sediments, and exchange with marine carbonates. So atmospheric input is important but not the sole source.
