Elemental carbon and nitrogen data for Skeletonema species as analyzed in Anderson and Rynearson, 2020

Abstract:

Elemental concentrations for Skeletonema species (n=2), as analyzed in Anderson and Rynearson, 2020. This dataset includes carbon, nitrogen, and volume measurements for S. marinoi (n=3) and S. pseudocostatum (n=4) evaluated at the thermal minimum, maximum, and optimum for each strain. Strains were isolated from Narragansett Bay, Rhode Island.

Description

This dataset includes carbon and nitrogen concentrations of Skeletonema cultures maintained at six temperatures. Strains were collected at Narragansett Bay, Rhode Island.

Methods & Sampling

Complete methods are outlined in Anderson and Rynearson, 2020, in press.

Elemental Analyses: From each culture and during exponential growth phase, >1 x 107 cells were filtered in triplicate onto precombusted 25-mm GF/F filters, and rinsed with 10 ml F/2 media. Blanks were made to correct for any elemental contribution from filters or media. Filters were dried at 60 degrees C for 24 hrs. The mass of the filter, total volume filtered, and cell counts were utilized to determine the number of cells analyzed. Elemental composition was assessed on an elemental analyzer.

Cell volume: Linear measurements of height and diameter were recorded for 30 live cells from each strain and used to calculate cell volume using the volume of a cylinder (Montagnes and Franklin 2001).

All data processing was carried out in R 3.4.1(R-Core-Team 2015).
