Salinity interdecadal variability in the western equatorial Pacific and its effects during 1950–2018

Radiocarbon variability in the western equatorial Pacific inferred from a highresolution coral record from Nauru Island

We have generated a high resolution coral A14C record spanning the last 50 years to document the seasonal and interannual redistribution of surface waters in the western tropical Pacific. Prebomb (1947-1956) A14C values average -63%0 and have a total range of 30%0. Values begin to increase in 1957, reaching a maximum of 137%o in mid-1983. Large interannual variability of up to 80%0 closely foll...

Defining the climatic signal in stream salinity trends using the Interdecadal Pacific Oscillation and its rate of change

The impact of landuse on stream salinity is currently difficult to separate from the effect of climate, as the decadal scale climatic cycles in groundwater and stream hydrology have similar wavelengths to the landuse pattern. These hydrological cycles determine the stream salinity through accumulation or release of salt in the landscape. Widespread patterns apparent in stream salinity are discu...

Pacific Interdecadal Climate Variability: Linkages between the Tropics and the North Pacific during Boreal Winter since 1900

This study examines the tropical linkages to interdecadal climate fluctuations over the North Pacific during boreal winter through a comprehensive and physically based analysis of a wide variety of observational datasets spanning the twentieth century. Simple difference maps between epochs of high sea level pressure over the North Pacific (1900–24 and 1947–76) and epochs of low pressure (1925–4...

Distribution of Virus-Infected Bacteria in the Western Equatorial Pacific

Viruses are generally considered an important agent of bacterial loss in diverse marine environments. However, the impact of viruses on bacteria is unknown in the western equatorial Pacific, where surface waters are warm and phytoplankton biomass is low (i.e., oligotrophic). Further, little is known about their importance in the mesopelagial, where bacteria and heterotrophic nanoflagellates are...
