Abstract:
This work is a continuation of the Tier 1 screening process to identify species of phytoplankton that are sensitive and resilient to oil and Corexit exposure. Cultures were grown of Micromonas pusilla, Tetraselmis astigmatica, Ochromonas sp., and other groups of phytoplankton that are underrepresented in the literature, but still important to the ecology of the Gulf of Mexico. Measurements of growth dynamics and photophysiology help to ascertain how these organisms respond to oil pollution.
Purpose:
This work was conducted to further understand what traits contribute to resistance to oil in marine phytoplankton. The species were selected to test a variety of traits such as motility, mixotrophy, cell size and the presence of a cell wall. This work can allow us to better predict how phytoplankton communities in the Gulf of Mexico might respond to future oil spills, and understand why different taxonomic groups respond so differently to oil exposure.

Description:
Dataset contains laboratory measurements of growth responses of specific phytoplankton species with
varying doses of oil and Corexit, no field sampling involved.
Supplemental Information:
Species: denotes the algal species the data is for (Mp = Micromonas pusilla; Ta = Tetraselmis astigmatica; Os
= Ochromonas sp., Hp = Heterocapsa pygmaea; Pm = Prorocentrum minimum)
Timepoint: units are in days
Treatment: the conditions the culture was grown in (C = control, f/2 seawater media; O = WAF, Water
Accommodated Fraction of oil; M = CEWAF, Chemically Enhanced Water Accommodated Fraction of oil; DM =
DCEWAF, Diluted Chemically Enhanced Water Accommodated Fraction of oil)
Replicate: each treatment was grown in triplicate, labelled A, B and C
EOE: Estimated Oil Equivalents, oil concentration measured in mg/L
Chl-a: Chlorophyll-a, measured in µg/L
Fv/Fm: the photosystem II (PSII) quantum yield, dimensionless
Sigma: PSII absorption cross-section, measured in Å2 (quanta)-1
p: PSII connectivity factor, dimensionless
Tau1: time constant of photosynthetic electron transport on the acceptor side of PSII, measured in µs
Tau2: time constant of photosynthetic electron transport between PSII and photosystem I (PSI), measured in
µs|Treatments were prepared using sterile seawater enriched with f/2 nutrients. WAF treatments were prepared
by adding Macondo crude oil to a target concentration of 1mg L-1, and CEWAF treatments were made with a
stock solution containing a 20:1 ratio of oil:Corexit. One third of the CEWAF was then diluted until the
crude oil concentration was consistent with the WAF to make the DCEWAF treatments. Control treatments were
not exposed to either oil or Corexit. The experiments were then set up in 1 L glass bottles and staged in a
climate-controlled chamber kept at 19° C. All treatments were grown in triplicate with true biological
replication. Every day, samples for EOE (5 mL), chlorophyll, and photophysiology (4 mL) were retrieved from
every experimental bottle. To each of the EOE samples, 15 mL of dichloromethane was added, and samples were
transferred to a fridge until analysis using a spectrophotofluorometer. The samples for chlorophyll and
photophysiology were left to dark-acclimate for ~10 minutes before being transferred into a FIRe
(Fluorescence Induction and Relaxation) system (Satlantic, Halifax, Canada). Parameters were collected from
both single turnover (ST) and multiple turnover (MT) curves, using 10 acquisitions per sample to reduce
noise. The sample was then recovered from the FIRe to measure the relative fluorescence intensity of
chlorophyll-a using a Turner fluorometer (Turner Designs, San Jose, USA).||9 mL of culture extracted every
24 hours.||
