Why was the data set created?

The Foraminiferal_Data.zip file includes all foraminiferal assemblage work from back-barrier and marsh wetlands collected on or around the Chandeleur Islands, Louisiana from March 2012 to July 2013 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center.

How was the data set created?

1. From what previous works were the data drawn?
2. How were the data generated, processed, and modified?

   Date: 2012 (process 1 of 4)

   Using a spatula, replicate samples (A and B) of surface sediment (0-2 cm) were collected at each sampling location and sealed in 50 ml centrifuge tubes. A solution of 2 g Rose Bengal per liter of ethanol was added to each centrifuge tube to stain the living protoplasm. The stained samples were transferred to the USGS SPCMSC foraminiferal Lab in St. Petersburg, FL. Person who carried out this activity:

   Date: 2012 (process 2 of 4)

   In order to ensure accurate staining, the samples were inverted daily over a period of two weeks. Prior to washing, the relative volume (ml) of sediment was recorded using the volume gradation on the tube (±1 ml). Each sample was washed over a 63 micron (µm) sieve under warm water; in some cases, an additional wash was necessary to remove clay particulates. The remaining sample (>63 µm size fraction) was oven-dried at 60°C to remove moisture and then reweighed to assess the weight of the sand fraction. Then, the dried sample was dry sieved to separate the 63-125 microns, 125-250 microns, and >250 microns sub-fractions. Person who carried out this activity:

   Date: 2012 (process 3 of 4)

   If more than 300 specimens were encountered in a sample, the sample was split using a micro-splitter. In most cases, the entire >125 micron fraction was spread across a 45-square, hole-punched tray, one or more times, for examination under a microscope. When a stained specimen (indicating the possibility that it was alive at collection) was encountered, it was picked up with a wet brush and dropped through a hole in the tray onto a stationary 60-square micropaleontological slide for later assemblage work (sorting and identification). Both A and B samples were picked, sorted, and counted individually and then later combined to provide a complete representation of the living foraminiferal community. Dead (non-stained) benthic foraminifera were picked onto the same micropaleontological slide and processed in the same manner as living specimens. Person who carried out this activity:

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?
   The foraminiferal assemblage work reported in the Excel spreadsheets, foraminineferal_data.zip, include count-only data for all samples. Foraminiferal density is calculated for each data set.
2. How accurate are the geographic locations?
   
3. How accurate are the heights or depths?
   
4. Where are the gaps in the data? What is missing?
   This is a complete, processed foraminiferal data file for the 12BIM01, 12BIM02, 12BIM05, and 13BIM06 core time series report.
5. How consistent are the relationships among the observations, including topology?
   The data include date of collection, stained or unstained, percent of sample examined, foraminiferal counts per species, number of foraminifers per sample, number of species, volume of sample used, and density of foraminifera.
