Abstract:

This dataset reports the water flux (epidermal and endodermal) over time for red mangrove roots analyzed by a sequential filtration model. A dual layer filtration model was used. This dataset supports the paper Berrin Tansel, Ariadna Arreaza, Derya Z. Tansel and Mengshan Lee (2015) Decrease in osmotically driven water flux and transport through mangrove roots after oil spills in the presence and absence of dispersants, Marine Pollution Bulletin, (98)1–2, 34-39, doi: 10.1016/j.marpolbul.2015.07.016.

Purpose:

To observe the water flux of mangrove roots exposed to Louisiana crude oil and Corexit 9500A dispersant.

Data Parameters and Units:

t= Time (days) delP1 = pressure differential across the membrane (epidermis) (atm) delP2 = pressure differential across the membrane (endodermis) (atm) A = membrane specific resistant coefficient (epidermis) B = membrane specific resistant coefficient (endodermis) k = fouling rate (1/day) k1 = fouling rate of epidermis (1/day) k2 = fouling rate of endodermis (1/day) 50% = specific fraction of water (50%)

Methods:

Water fluxes were calculated using the following equations: For epidermis: Jt1/Jo1 = 1/(a1 + b1e^k1t) For endodermis: Jt2/Jo2 = n[1/(a1 + b1e^k1t)][1/(a2 + b2e^k2t)].
