Small rivers and/or streams that drain the mountainous areas in these climatic zones deliver the majority of the sediment and nutrient inputs to these narrow shelf environments; such inputs often occur as discrete, episodic introductions associated with storm events. To gain insight into the linked biogeochemical behavior of subtropical/tropical mountainous watershed-coastal ocean ecosystems, this work describes the use of a buoy system to monitor autonomously water quality responses to land-derived nutrient inputs and physical forcing associated with local storm events in the coastal ocean of southern Kaneohe Bay, Oahu, Hawaii, USA. The data represent 2.5years of near-real time observations at a fixed station, collected concurrently with spatially dist...

These data represent 2.5 years of near-real time observations at a fixed station, collected concurrently with spatially distributed synoptic sampling over larger sections of Kaneohe Bay, Oahu, Hawaii. Nutrient loadings from direct rainfall and/or terrestrial runoff produce an immediate increase in the N:P ratio of bay waters up to 48, and drive phytoplankton biomass growth. Rapid uptake of nutrient input subsidies by phytoplankton causes a rapid decline of pCO2 and nitrogen, before a return to baseline levels with the subsequent decline of phytoplankton biomass over time scales ranging from a few days to several weeks, depending on the conditions and proximity to the sources of runoff. This work exemplifies the utility of combining synoptic sampling and real-time autonomous observations to el...
