Abstract. Accurate assessment of anthropogenic carbon dioxide (CO2) emissions and their redistribution among the atmosphere, ocean, terrestrial biosphere in a changing climate – “global budget” is important to better understand global cycle, support development policies, project future change. Here we describe synthesize data sets methodology quantify five major components budget uncertainties. Fossil CO2 (EFOS) are based on energy statistics cement production data, while from land-use...

We have performed an in situ test of the iron limitation hypothesis subarctic North Pacific Ocean. A single enrichment dissolved caused a large increase phytoplankton standing stock and decreases macronutrients carbon dioxide. The dominant species shifted after addition from pennate diatoms to centric diatom, Chaetoceros debilis, that showed very high growth rate, 2.6 doublings per day. conclude bioavailability regulates magnitude biomass key determine biogeochemical sensitivity supply...

Iron is an essential nutrient and plays important role in the control of phytoplankton growth (Martin et al., 1989). Atmospheric dust has been thought to be most source iron, supporting annual biological production western subarctic Pacific (WSP) (Duce Tindale, 1991; Moore 2002). We argue here for another iron WSP. found extremely high concentrations dissolved particulate Okhotsk Sea Intermediate Water (OSIW) North (NPIW), water ventilation processes this region probably transport through...
Abstract. The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity dioxide) products for surface oceans. Version 2 SOCAT is update previous release (version 1) with more data (increased from 6.3 million 10.1 water values) extended coverage (from 1968–2007 1968–2011). quality control criteria, while identical in both versions, have been applied strictly version than 1. website...

30‐years time series of AOU and phosphate in the Oyashio sub‐surface domain showed an increasing trend superimposed on bidecadal oscillation. isopycnals between 26.7 27.2 σ θ increased by average 0.9±0.5 0.005±0.003 µmol/kg/y, respectively. Salinity these also linear increase 0.0008 psu/y. density winter mixed layer, other hand, was found to have decreased during observation period.

This work presents an estimate of anthropogenic CO 2 in the Pacific Ocean based on measurements from WOCE/JGOFS/OACES global survey. These estimates used a modified version ΔC* technique. Modifications include revised preformed alkalinity term, correction for denitrification, and evaluation disequilibrium terms using optimum multiparameter analysis. The total inventory over area 120°E to 70°W 70°S 65°N (excluding South China Sea, Yellow Japan/East Sea Okhotsk) was 44.5 ± 5 Pg C 1994....
Multiyear (2003Multiyear ( -2008) ) time series observations along the A line provided information on temporal variability of dissolved iron (diss-Fe) concentration in Oyashio region western subarctic Pacific, and data indicated that there was an annual cycle surface diss-Fe occurring every year.Diss-Fe supplied into water this winter supports spring phytoplankton bloom after development thermocline.The drawn down during period depleted summer some masses.Then increased from autumn to with...
Enormous quantities of radionuclides were released into the ocean via both atmospheric deposition and direct release as a result Fukushima Dai-ichi Nuclear Power Plant (FNPP) accident. This study discusses southward dispersion FNPP-derived radioactive cesium (Cs) in subsurface waters. The southernmost point where we found (134)Cs (1.5-6.8 Bq m(-3)) was 18 °N, 135 °E, September 2012. potential density at peaks (100-500 m) increased water column inventories (137)Cs between 0 500 m after winter...
Abstract. A strong oxygen-deficient layer is located in the upper layers of tropical Pacific Ocean and deeper North Pacific. Processes related to climate change (upper-ocean warming, reduced ventilation) are expected ocean oxygen nutrient inventories. In most basins, a decrease (“deoxygenation”) an increase nutrients have been observed subsurface layers. Deoxygenation trends not linear there could be multiple influences on variability. Here time series since 1950 were investigated at 50 300...
