Siderophore cycling in the North Pacific Subtropical Gyre
… in the upper 1000 m of the US GEOTRACES GP15 Pacific Meridional Transect. Siderophore concentration ranges from 0-70 pM, and there is no correlation between the concentration of siderophores and dissolved Fe (dFe, <0.2 μm). In contrast, most siderophore hotspots, defined by concentration that …

Trace Metal Biogeochemistry in the Western North Pacific
… Mn, Ni Zn and Pb across the western and central North Pacific.</p> <p>Dissolved trace metal concentrations were measured using a novel isotope dilution-ICP-MS method after extraction over an 8-hydroxyquinoline resin column and validated through the use of the SAFe consensus reference materials. …

Determination of dissolved trace metals in the western North Pacific
… used to investigate trace metals in the western North Pacific, a region for which little trace metal data are available. Concentrations of these elements are found to be in the range of 0.7 pmol/kg to 12nmol/kg, analytical precision is better than 7%, and the seawater detection limits are in the …

Dimensions of microbial biodiversity in the North Pacific subtropical Gyre
… a long-term study site representative of the North Pacific Subtropical Gyre (NPSG). We observed changes in diversity and community composition at Station ALOHA across time, ocean depth and on plastic debris, a new anthropogenically derived niche in the NPSG. Despite surface waters only …

The effect of eddies on fCO₂ in the North Pacific surface ocean
… the impact of mesoscale eddies in the North Pacific on surface ocean fCO₂ using the in-situ measurements from the Surface Ocean CO₂ Atlas (SOCAT) to inform the importance of the mesoscale dynamics on global CO₂ fluxes. We sort SOCAT measurements from 2000-2019 by whether or not they are …

Relationships between global warming and tropical cyclone activity in the Western North Pacific
… and tropical cyclone activity in the Western North Pacific (WNP). Our hypothesis is that global warming impacts on TC activity occur through changes in the large scale environmental factors (LSEFs) known to be important in determining the formation and intensity of TCs. The LSEFs on which we …

Understanding the CO₂cycle in the North Pacific Ocean using inverse box models
… better able to close the tracer budgets in the North Pacific than the Levitus section. The transport calculations showed that highly resolved hydrographic data are necessary to accurately determine the tracer transports, and pointed out the sensitivity of the calculation to errors in the Ekman …

Regulation of Glucose Uptake and Transporter Expression in the North Pacific Spiny Dogfish (Squalus suckleyi)
… their expression were investigated in the North Pacific spiny dogfish (Squalus suckleyi). In particular, the presence of a putative GLUT4 transporter, which was previously thought to have been lost in these fish, was established and its mRNA levels were shown to be upregulated by feeding …

Physical Oceanographic Controls on Biological Production and Ocean-Atmosphere Carbon Flux in the North Pacific
… in which they occur. Both processes occur in the North Pacific transition zone (NPTZ), a basin-wide region near the subpolar-subtropical gyre boundary. </p><p>First, this work investigates the physical forcing behind the large seasonal variability in the location of the Transition zone chlorophyll …

Development and application of an analog scheme for predicting the intensification of Western North Pacific tropical cyclones
… for forecasting intensity changes of Western North Pacific tropical cyclones using an analog forecast scheme. A number of procedures were devised to quantitatively define the forecast potentials of these parameters in a systematic method. Based on the results of these procedures, predictors …

Interannual variability in cloudiness, sea surface temperature, and atmospheric circulation over the midlatitude North Pacific during summer
… (SST) are closely coupled over the central North Pacific during summer. Increased (decreased) MSC amount occurs with decreased (increased) SST, resulting from coincident meridional shifts in the regions of strong SST gradient and cloud gradient between subtropics and midlatitudes. …

Anomalous carbonate preservation in the abyssal North Pacific, ODP sites 882 and 1179: planktonic foraminiferal analysis, climate change and palaeogeomagnetism /
… study were obtained from the abyssal western North Pacific Ocean at Ocean Drilling Project Sites 882 (50°21.797'N, 167°35.999^E) and 1179 (41°4.787^N, 159°58.786'E). Despite their depth below the present day calcite compensation depth, ~250m and ~ 1.5km respectively, these late …

An Observational and Modeling Study of the Relationships Between United States Precipitation and Pacific Sea Surface Temperature
… U.S. precipitation in response to prescribed North Pacific SST anomalies, related to Great Plains precipitation. Summer precipitation is enhanced throughout the U.S. due to SST anomalies. The increase in precipitation is caused by enhanced low-level moisture flux, strong upper-level cyclonic …
