(she/her)Julia Seidenstein is a Geologist at the Florence Bascom Geoscience Center.
Julia Seidenstein is a geologist at the USGS Florence Bascom Geoscience Center in Reston, VA. Julia operates the GeoTek Multi-Sensor Core Logger Facility, to take non-destructive measurements and capture high resolution images of sediment cores collected from Alaska to Florida by USGS scientists. Julia is experienced in foraminifera analyses of sediment cores and has worked on projects from the Arctic to the Antarctic to reconstruct ocean conditions of the past.

Holocene Sea-Level Variability from Chesapeake Bay Tidal Marshes
We reconstructed the last 10,000 years of Holocene relative sea-level rise (RSLR) from sediment core records in near Chesapeake Bay, eastern U.S.A., including new marsh records from the Potomac and Rappahannock Rivers, Virginia. Results show mean RSLR rates of 2.6 mm yr-1 from 10 to 8 kilo-annum (ka) due to combined final ice-sheet melting during deglaciation and glacio-isostatic adjustment (GIA

The benthic foraminifera cassidulina from the Arctic Ocean: Application to paleoceanography and biostratigraphy
We investigated the morphology, biostratigraphy, shell stable isotope composition and paleogeography of the common Arctic benthic foraminifera, Cassidulina teretis (Tappan 1951) (sometimes assigned to Islandiella (Nørvang 1958), for application to Quaternary paleoceanography. Cassidulina teretis, which has been studied by several generations of Arctic foraminiferal specialists, is used in Arctic

Late Holocene paleoceanography in the Chukchi and Beaufort Seas, Arctic Ocean, based on benthic foraminifera and ostracodes
Calcareous microfossil assemblages in late Holocene sediments from the western Arctic continental shelf provide an important baseline for evaluating the impacts of today’s changing Arctic oceanography. This study compares 14C-dated late Holocene microfaunal assemblages of sediment cores SWERUS-L2-2-PC1, 2-MC4 and 2-KL1 (57 mwd), which record the last 4200 years in the Herald Canyon (Chukchi Sea sh
