||Microplastic was collected using a standard manta net tow. (link: http://swfsc.noaa.gov/textblock.aspx?Division=FRD&ParentMenuId=213&id=1342). Each sample was sorted at 6-12x magnification under a Wild M-5 dissecting microscope, and plastic particles removed for further analysis. Plastic particles were soaked in deionized water to remove salts, dried at 60°C, and stored in a desiccator. Dry mass was measured on an analytical balance. Particles were then digitally imaged with a Zooscan digital scanner (Gorsky et al. 2010). The total number of particles was measured using NIH ImageJ-based tools in the Zooprocess software, calibrated against manual measurements (Gilfillan et al. 2009, Gorsky et al. 2010).
This dataset is compiled from data collected during research cruises conducted and funded by different agencies. Please refer to the particular study metadata and accompanying documents for differences in methodologies, or contact the current provider for this dataset.
Not every column applies to all studies, but are included because of the tabular format in which these data are stored. The following specifies which fields are non-applicable to which studies:
Event Index, Event Number, Tow Number, Halobates Abundance, Halobates Egg Abundance
Event Number, Grid Line, Grid Station
Tow Number, Grid Line, Grid Station
