Coastal urbanization alters carbon cycling in Tokyo Bay.

ABSTRACT: The carbon budget of Tokyo Bay, a highly urbanized coastal basin, was estimated using a box model that incorporated inorganic and organic carbon data over an annual cycle (2011-2012). The surface water represented net autotrophic system in which the annual net community production (NCP) was 19 × 10¹⁰ gC year^-1. The annual loading of dissolved inorganic carbon and total organic carbon (TOC) from freshwater inputs was 11.2 × 10¹⁰ and 4.9 × 10¹⁰ gC year^-1, respectively. The annual TOC sedimentation rate was 3.1 × 10¹⁰ gC year^-1, similar to the annual air-sea CO₂ uptake (5.0 × 10¹⁰ gC year^-1). Although the NCP and TOC loading from freshwater inputs were respectively 3.0 and 2.7 times l
