Numerical and mass concentrations of microplastic debris collected by manta net; Numerical concentrations of Halobates sericeus adults/juveniles and eggs; zooplankton biomass concentration. Various cruises from 1972 - 2010 (completed).
Microplastic, Halobates, and zooplankton were collected using a standard manta net tow. Each sample was sorted at 6-12x magnification under a Wild M-5 dissecting microscope, and plastic particles and H. sericeus 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). H. sericeus samples were enumerated and classified into 5 categories: juvenile, adult male, adult female, newly molted, and molted exoskeletons. H. sericeus eggs, both those attached to plastic and those that had become detached during the collection process, were also enumerated. Dry mass of zooplankton was obtained from preserved manta tow samples. After fixation in 1.8% formaldehyde for 24 months, samples were split in a Folsom splitter, filtered onto 202 µm Nitex mesh disks and rinsed with isotonic ammonium formate. Filters were dried for 24 hours at 60°C and placed in a vacuum dessicator until weighing. Filters were weighed to the nearest 0.0001 gram on the same analytical balance as the plastic samples. A 20% correction factor was applied in order to compensate for the biomass lost by preservation.

Upscaling capillary pressure curves for numerical modeling of gravity-capillary driven flow
<p>This work investigates upscaling of capillary pressure curves for modeling gravity segregation under the influence of capillary heterogeneity. We consider two flowing phases driven by gravity and capillary forces and seek the saturation spatial and temporal variation until equilibrium is reached. Existing upscaling methods, found in the literature, are applied to a number of cases. Resulting saturation solutions are compared to fine-scale simulations and the different methods are evaluated, showing in general that the popular capillary limit method produces the best results. However, a large number of cases are found to have significant errors. This leads to the conclusion that existing methods are often inadequate. We therefore propose a new optimization-based upscaling method. Using this approach it is shown that capillary pressure can be upscaled to Brooks-Corey type functions and produce accurate upscaled simulations matching the fine-scale solutions. Optimization upscaling is computationally demanding and requires the fine-scale simulations for minimizing an objective function. However, it is shown that the upscaled curves are robust, i.e., they can be applied to different permeability realizations to calculate ensemble average saturation solutions.<br> </p>
