Description:
Abstract:
Data later consists of Nearshore Ecological Data Atlas Planning Grid populated with the results of Marxan analyses for the Marine Habitat target group. A series of Marxan scenarios comprised of 100 runs, with 10,000,000 iterations each, were completed. A best iteration was selected from each run, and a "Sum" solution resulted, which depicts how often within the 100 runs a planning grid cell was in a best iteration.
Purpose:
This dataset is designed to depict areas of natural resource concentration in Oregon's marine environment. The planning grid was developed by NOAA's Biogeography Branch and The Nature Conservancy in Oregon as a common index for modeling efforts in development of the Oregon Dept. of Fish and Wildlife's (ODFW) Nearshore Ecological Data Atlas.
Supplemental Information:
"Sum" solution scores are an indication of the relative importance of the species/habitats within a planning grid cell towards meeting the benchmarks for that group. A score of 100, for example, indicates the benchmarks for a group cannot be achieved without the species/habitats within that grid cell. Similarly, a score of 0 means the species/habitats within that grid cell are not required to meet the benchmarks for that group.

Source Time Period of Content:
Source Contribution:
Spatial information for Seafloor habitats (Benthic substrate classes) of all types by assessment unit.
Benthic habitats were grouped into 4 classes; sand, mud, rock and mixed. Kelp data (AL0100) were used to augment the rock class with some small additional areas missed by the OSU benthic habitat mapping team. The final map of classes was then dissolved into singlepart features. Bathymetry data (HA0400) were reclassified into 5 classes; 0 - 30 meters of depth, 30 - 60 meters of depth, 60 - 200 meters of depth, 200 - 700 meters of depth, and gt 700 meters of depth. This reclassified raster was vectorized and then intersected with the benthic habitats to create a substrate x depth class dataset. This was subsequently intersected with the planning grid and hectares of each substrate x depth class were calculated for each AU. The rock substrate types were stratified into separate targets based upon the north/south split within the territorial sea, and rock substrates beyond the TS. Rock was analyzed as part of the "Fish" group in Marxan as a proxy for rock fish, as a habitat type within the "Habitat" Marxan run, and as part of the "Al Target" Marxan run.

Title: Kelp Canopy composite from all kelp surveys (1990, 1996-99, 2010)
Source Time Period of Content:
Source Contribution:
This layer was created from the other individual year kelp surveys to show the maximum known extent of Oregon's kelp canopy. Included are: an Oregon coastwide inventory of canopy kelp in 1990, that was conducted to understand the distribution of kelp in the nearshore region, and five other years of southern Oregon surveys 1996-99, 2010.
Data were intersected with the planning grid and hectares x AU were calculated. Marxan target codes were assigned based upon north/south stratification of the territorial sea.

Source Time Period of Content:
Source Citation Abbreviation: Chlorophyll-a density category by assessment unit
Source Contribution:
Chlorophyll-a concentrations characterised during summer months (June-September) from 1998-2005. Derrived from SeaWiffs satelite 1.1km resolution monthly composites of chlorophyll-a.
Chlorophyll-a was mapped across the region from satellite data. Based upon advice from the NEDA Scientific Advisory Board, the continuous values were binned into 5 categories. The raw Chlorophyll-a raster was then reclassified into these bins, and zonal statistics (majority) were used to impute a category to each AU. These bins were then stratified into Marxan targets based upon the divide across the TS/EEZ line resulting in 9 Marxan targets for
chlorophyll-a.

Source Citation Abbreviation: Upwelling persistence by assessment unit
Source Contribution:
High persistence upwelling areas characterised during the upwelling season (June-Aug) from 1998-2004. Derrived from AVHRR satelite 1.1km resolution monthly composites of SST.
Satellite imagery from 1998 - 2004 was used to identify upwelling persistence across the study area. Based upon advice from the NEDA Scientific Advisory Board, the continuous values were binned into 2 categories, high persistence and low persistence. The raster was reclassified into these two categories, then zonal statistics were used to impute the majority class to each AU, which was then assigned a "1" denoting presence of upwelling within that class. The upwelling targets were then stratified by the TS/EEZ line to derive the 4 final upwelling targets used in Marxan.

Title: Historical dissolved oxygen data off Oregon: 1950-80
Source Time Period of Content:
Source Citation Abbreviation: Dissolved oxygen category by AU
Source Contribution:
Near-bottom (within10 m or 15% of bottom depth) dissolved Oxygen levels during the late-upwelling-seasons (July-Sept.) of 1950-1980 . Derrived from the National Ocean Data Center's World Ocean Database.
Measurements of dissolved oxygen over a 30 year time span were interpolated to derive estimates of O2 ml / L across the region. Based upon advice from the NEDA Scientific Advisory Board, the continuous values were binned into 3 categories. The raw dissolved oxygen raster was then reclassified into these bins, and zonal statistics (majority) were used to impute a category to each AU. These bins were then stratified into Marxan targets based upon the divide across the TS/EEZ line resulting in 5 Marxan targets for dissolved oxygen.
Process Step:
Process Description:
Each feature class listed in this document was summarized by the assessment units. Four general classes of data were used, each with a slightly different method of interpolation to this planning grid. An overview of those four methods will be given here, but more specific information will be listed for each input in the 'sources' > 'source Citation Detail' portion of this document.
Rasters of continuous data (i.e. PRBO species distributions) were typically resampled to 90 meters. Zonal statistics were then used to impute a min, mean and max value for each assessment unit. Mean values were then normalized and used as the Marxan abundance.
Rasters for continuous data that were binned into categories (i.e. Upwelling) were first reclassified into their categories, then resampled to 90 meters. Zonal statistics were then used to imput a majority value for each assessment unit. The assessment unit was then assigned to the majority bin, and it's abundance was calculated as "1" for presence.
Vectors of probability or density data (i.e. NOAA Southwest Fisheries Science Center Cetacean distributions) were intersected with the planning grid, then an area weighted value was calculated to impute a single abundance value for the AU as (Value1 * Percentage AU of 1) + (Value 2 * Percentage AU of 2)...+ (Value N *Percentage AU of N).
Vectors for discrete physical features (i.e. benthic habitats) were intersected with the planning grid and the area (hectares) of each discrete feature within the AU was calculated.
Abundance values used in Marxan were generally adjusted to a 0- 100 scale. Raw area values, for targets such as benthic habitats and kelp, were calculated in hectares to keep them in a similar range (0 - 256). Values less than 0.01 were not used in the Marxan analysis for any target.
