The paper “A Holocene record of ocean productivity and upwelling from the northern California continental slope” was published in Quaternary International.Below are the interactive maps. Because it is difficult to extrapolate these local data to the entire 3,000-km-long region, this work highlights the continued need for paleoceanographic exploration of the North Pacific Ocean. This result supports projections of future upwelling intensification along the US West Coast. pollen an indirect indicator of upwelling as well.Ĭomparing these new upwelling data against a nearby pre-existing record of Holocene sea surface temperatures (SST), the study found that the onset of modern California upwelling occurred at the same time as an approximate +1.5☌ warming. Coastal redwood trees collect much of their moisture from fog, which is associated with spring and summer upwelling, thus making the presence of Sequoia sp. These results were further verified by both marine and terrestrial microfossil indicator species within the same sediment samples: a diatom associated with coastal upwelling conditions ( Rhizosolenia sp.), and pollen from the coastal redwood ( Sequoia sp). (modified from Figure 9 in Addison et al., 2017). The dashed red line indicates the onset of modern California coastal upwelling at ~2900 cal yrs BP, with the width of the light rectangle scaled to represent the 95% age confidence level (2720-3060 cal yrs BP).

Productivity and upwelling data from TN062-O550 and nearby ODP site 1019. There are 1,741 active zip codes in California. This same interval is also identified as the onset of “modern” upwelling along the California margin.įigure 2. Statistical analyses of these data discovered that upwelling intensity along the northern California margin has undergone at least four shifts since the early Holocene, with the most intense upwelling period starting at ~2900 calibrated years before present (cal yr BP) and extending into modern times (Fig. Several key measurements were made, including opal concentrations (a proxy for diatom productivity, which is one of the key phytoplankton groups that make up the base of the California marine food web) and stable ð 13C and ð 15N isotope measurements (proxy indicators of nutrient cycling in the water column). To better understand future upwelling dynamics under predicted warmer North Pacific Ocean conditions, a team of researchers from the USGS, Idaho State University, the Lamont-Doherty Earth Observatory, and the Skidaway Institute of Oceanography analyzed a marine sediment record from the northern California continental slope (569 m water depth) that spans the last 7,500 years as a potential analogue for future conditions.
