This data contains information specifically for the Arctic Nearshore Impact Monitoring in the Development Area (ANIMIDA 1999 - 2002) and continuation of Arctic Nearshore Impact Monitoring in the Development Area (cANIMIDA 2004 - 2007) programs in the Alaskan Beaufort Sea. Minerals Management Service (MMS) initiated these studies to characterize the pre and post construction environmental impacts surrounding the offshore oil development and production activities in this area. The data encompasses the following areas from 1999 thru 2007: 1) Hydrocarbon and Metal characterization of sediments. Sediments were collected and analyzed for a variety of parameters including Organics (PAH, SHC, and S/T), Grain size, TOC, trace metals and radionuclides (Pb210 and Cs137). 2) Sources, Concentrations and dispersion pathways for suspended sediment and 3) Partitioning of potential contaminants between dissolved and particulate phases. These two tasks focused on suspended sediments and the dissolved / particulates in the water column in fresh and salt water and ice cores. The study analyzed for both chemical and physical parameters that included insitu CTD measurements, POC, DOC, trace and major metals. 4) Biomonitoring and bioaccumulation of contaminants in biota. The biota studied included amphipods, isopods, clams, fish, mussels and SPMD. These tissues were analyzed for metals, PAH, PAH exposure biomarkers (cytochrome P450 1A (CYP1a) and bile fluorescent aromatic compounds (FAC)). 5) Monitoring the Boulder patch area. This area of the program studied the benthic community and kelp biomass. Parameters of interest included: PAR, light attenuation, TSS, kelp productivity and biomass and benthic faunal diversity. Additional analysis for water column chlorophyll, nutrients and CTD parameters were also conducted.
