New evidence based on recent satellite data is presented to provide a rare opportunity in quantifying the long‐speculated contribution of tropical cyclones enhance ocean primary production. In July 2000, moderate cyclone Kai‐Tak passed over South China Sea (SCS). During its short 3‐day stay, triggered an average 30‐fold increase surface chlorophyll‐a concentration. The estimated carbon fixation resulting from this event alone 0.8 Mt, or 2–4% SCS's annual new Given 14 passing SCS annually, we...
A distinctive seasonal pattern in phytoplankton biomass was observed at the South East Asian Time‐series Study (SEATS) station (18°N, 116°E) northern China Sea (SCS). Surface chlorophyll‐ a , depth‐integrated and primary production were elevated to 0.3 mg/m 3 ∼35 2 300 mg‐C/m /d, respectively, winter but stayed low, ≤0.1 ∼15 110 /d as commonly found other low latitude waters, rest of year. Concomitantly, soluble reactive phosphate nitrate+nitrite mixed layer also became readily detectable...
The atmospheric flux of 7 Be over a 2‐year period at coastal site (Norfolk, Virginia) and an inland (Oak Ridge, Tennessee) typically supports inventories ranging from 1.0 to 2.0 pCi/cm 2 (1 pCi = 0.037 Bq), with the highest generally occurring in spring lowest fall. calculated average daily fluxes required support these range 0.013 0.026 cm −2 d −1 . Despite different production‐source terms for 210 Pb, there is high degree correlation between their measured total monthly deposition...
With the rapid rise in pollution-associated nitrogen inputs to western Pacific, it has been suggested that even open ocean affected. In a coral core from Dongsha Atoll, remote reef ecosystem, we observe decline 15N/14N of skeleton-bound organic matter, which signals increased deposition anthropogenic atmospheric N on and its incorporation into plankton and, turn, atoll corals. The first clear change occurred just before 2000 CE, decades later than predicted by other work. amplitude suggests...
Abstract A 2 °C increase in global temperature above pre-industrial levels is considered a reasonable target for avoiding the most devastating impacts of anthropogenic climate change. In June 2015, sea surface (SST) South China Sea (SCS) increased by response to developing Pacific El Niño. On its own, this moderate, short-lived warming was unlikely cause widespread damage coral reefs region, and reef “Bleaching Alert” alarm not raised. However, on Dongsha Atoll, northern SCS, unusually weak...
Abstract Coral reefs are built of calcium carbonate (CaCO 3 ) produced biogenically by a diversity calcifying plants, animals, and microbes. As the ocean warms acidifies, there is mounting concern that declining calcification rates could shift coral reef CaCO budgets from net accretion to dissolution. We quantified ecosystem (NEC) production (NEP) on Dongsha Atoll, northern South China Sea, over 2 week period included transient bleaching event. Peak daytime pH wide, shallow flat during...
Abstract Internal waves can influence water properties in coastal ecosystems through the shoreward transport and mixing of subthermocline into nearshore region. In June 2014, a field experiment was conducted at Dongsha Atoll northern South China Sea to study impact internal on coral reef. Instrumentation included distributed temperature sensing system, which resolved spatially temporally continuous measurements over 4‐km cross‐reef section from lagoon 50‐m depth fore Our observations show...
Atmospheric depositional fluxes of 7 Be and 210 Pb were measured simultaneously in wet‐only bulk deposition over a 29‐month period (October 1982 through February 1985) Norfolk, Virginia (36°53′N, 76°18′W). Total precipitation accumulation during 1983 1984 was 134 129 cm, respectively, slightly above the normal yearly accumulation. The volume‐weighted average concentrations for 90 100 dpm/L, while those 5.9 6.6 respectively. annual 12.0 12.9 dpm/cm 2 (for Be) 0.79 0.85 Pb), There high degree...

Significance Biologically available nitrogen (fixed N) limits the fertility of much ocean. Of processes that remove fixed N from ocean, conversion to 2 in coastal sediments appears dominate. This work provides strongest data-based support for long-standing hypothesis changes loss along ocean margin due cyclic drowning and emergence continental shelves. The data also imply strong local coupling fixation, dominant input thus suggesting a stable oceanic reservoir over glacial cycles. Finally,...
