Spatial Provinces and Domains of the Central Valley for Textural Analysis


This digital dataset contains the 9 major areas used to subdivide the Central Valley for the interpolation of the 
percentage of coarse-grained deposits into the texture model.  This texture model was used as input data for 
the hydraulic properties portion of the Central Valley Hydrologic Model (CVHM).  The Central Valley encompasses 
an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central 
Valley is simulated using the USGS numerical modeling code MODFLOW-FMP (Schmid and others, 2006).  
This simulation is referred to here as the CVHM (Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates 
groundwater and surface-water flow, irrigated agriculture, land subsidence, and other key processes in the Central 
Valley on a monthly basis from 1961-2003.  The total active modeled area is 20,334 square-miles on a finite 
difference grid comprising 441 rows and 98 columns. Slightly less than 50 percent of the cells are active. The 
CVHM model grid has a uniform horizontal discretization of 1x1 square mile and is oriented parallel to the valley 
axis, 34 degrees west of north (Faunt, 2009). In order to better characterize the aquifer-system deposits, lithologic 
data from approximately 8,500 drillers' logs of boreholes ranging in depth from 12 to 3,000 feet below land surface 
were compiled and analyzed. The percentage of coarse-grained sediment, or texture, then was computed for each 
50-foot depth interval of the drillers' logs. A 3-dimensional texture model was developed by interpolating the percentage 
of coarse-grained deposits onto a 1-mile spatial grid at 50-foot-depth intervals from land surface to 2,800 feet below 
land surface. The CVHM is the most recent regional-scale model of the Central Valley developed by the U.S. Geological 
Survey (USGS).  The CVHM was developed as part of the USGS Groundwater Resources Program (see "Foreword", 
Chapter A, page iii, for details).

A Digital Hydrologic Network Supporting NAWQA MRB SPARROW Modeling--MRB_E2RF1WS


A digital hydrologic network was developed to support SPAtially Referenced Regression on Watershed 
attributes (SPARROW) models within selected regions of the United States. These regions correspond 
with the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program Major River 
Basin (MRB) study units 2, 3, 4, 5, and 7 (Preston and others, 2009).  MRB2, covers the South 
Atlantic-Gulf and Tennessee River basins.  MRB3, covers the Great Lakes, Ohio, Upper Mississippi, 
and Souris-Red-Rainy River basins.  MRB4, covers the Missouri River basins.  MRB5, covers the 
Lower Mississippi, Arkansas-White-Red, and Texas-Gulf River basins.  MRB7, covers the Pacific 
Northwest River basins. 
		
The digital hydrologic network described here represents surface-water pathways (MRB_E2RF1) 
and associated catchments (MRB_E2RF1WS). It serves as the fundamental framework to spatially 
reference and summarize explanatory information supporting nutrient SPARROW models (Brakebill 
and others, 2011; Wieczorek and LaMotte, 2011). The principal geospatial dataset used to support 
this regional effort was based on an enhanced version of a 1:500,000 scale digital stream-reach 
network (ERF1_2) (Nolan et al., 2002). Enhancements included associating over 3,500 water-quality 
monitoring sites to the reach network, improving physical locations of stream reaches at or near 
monitoring locations, and generating drainage catchments based on 100m elevation data.
		
A unique number (MRB_ID) identifies each reach as a single unit. This unique number is also shared 
by the catchment area drained by the reach, thus spatially linking the hydrologically connected 
streams and the respective drainage area characteristics. In addition, other relevant physical, 
environmental, and monitoring information can be associated to the common network and accessed 
using the unique identification number.

Mid-Depth Rocky & Soft-Bottom Ecosystems, California South Coast MPA Baseline Study, 2011 to 2012

Seafloor habitats deeper than 100 meters make up an estimated 29% (1840 km2) of state waters in southern California, yet they are sampled with far less frequency when compared to shallower waters due to the many challenges associated with sampling in deep water. This difference in the frequency of sampling is concerning given the many economically and ecologically important organisms, along with the unique and productive habitats in which they occur, that are found below 100 m. With the creation of the new network of marine protected areas, over 35% (330 km2) of the State’s shelf and slope deeper than 100 m are now protected within State Marine Reserves and
Conservation Areas.

This dataset represents a multi-year study (September 2011 – January 2015) to characterize mid-depth rocky reef and soft bottom ecosystems in the California Marine Life Protection Act’s South Coast (SC) Study Region. The specific objective was to characterize the seafloor habitats and associated biological communities within and adjacent to the State Marine Reserves (SMRs) and Conservation Areas (SMCAs) at the time of implementation.

Rocky Intertidal Ecosystems, California North Coast MPA Baseline Study

The objectives of this baseline study of rocky intertidal habitats along the North Coast Study Region (NCSR) are to (1) produce a quantitative baseline characterization of the structure of rocky intertidal ecosystems in Marine Protected Areas (MPAs) established by the Marine Life Protection Act (MLPA), (2) provide an initial comparison between rocky intertidal ecosystems inside MPAs and nearby associated (unprotected) reference areas, (3) analytically explore baseline characterizations for potential indicators of the state of rocky intertidal ecosystems, (4) generate a fish biodiversity baseline within rocky tide pools at a few sites inside and outside of MPAs (for the first time) as well as (5) examine rockfish recruitment into these tide pools, and (6) integrate these assessments with other components of the baseline survey, including (7) high resolution topographic geological surveys, to inform the role and design of these programs for future monitoring and evaluation of MPAs.

Shallow Rock and Kelp Forest Ecosystems, California South Coast MPA Baseline Study, 2011 to 2012

We systematically surveyed 94 of the 122 nearshore rocky reefs in the California south coast study region (SCSR). This synoptic baseline survey was conducted at 75 individual sites in 2011 and 88 sites in 2012. In addition, we incorporate two similar ‘historical’ data sets from 59 sites in 2004 and 79 sites in 2008. From 2011-2012, we surveyed all accessible nearshore rocky reefs found in the SCSR MPAs and determined the appropriateness of references areas for each. This baseline provides, for the first time, a taxonomically exhaustive biogeographic assessment of the nearshore subtidal reefs in the SCSR, improving significantly on our knowledge of the region and incorporating newly established and existing MPAs. Results confirm previously described patterns for subtidal fishes, reflect the physical oceanographic complexities of the Southern California Bight and add new knowledge to biogeographic patterns of algae and invertebrates. The SCSR is characterized by strong environmental gradients, a major defining feature of the SCSR compared to the other California MLPA Study Regions that have relatively more spatially consistent physical environments. These differences are reflected biologically in a high degree of kelp forest community structure across the region. We identified 17 geographically cohesive community clusters, each with distinct fish, invertebrate, and algal assemblages (Figure ES.1). Although kelp forest communities in the SCSR are highly variable, the structure can be related to the sea surface temperature patterns caused by the confluence of the California Current, the Southern California Counter Current and localized upwelling. Benthic habitat structure also varies within the region; the geology and structure of island reefs are functionally different from mainland reefs. Mainland reefs generally are less steep, can be found significantly offshore of the coastline, and have a greater influence of sedimentation moving through the system. With few exceptions, island reefs are generally abrupt, high relief structures, tightly fit to the coastline with less influence of the nearby soft bottom habitat. Ideally, long-term monitoring of MPAs should be distributed across the distinct areas as each is likely to respond differently.

Nearshore Rocky Reefs and Kelp Forests, California North Coast MPA Baseline Study, 2014 to 2015

Here we provide one of the first systematic, “snapshot” surveys of the entire North Coast Study Region, from the Oregon border to the headland at Point Arena. Our attempt was to characterize these subtidal rocky reefs both inside of the newly created MPAs throughout the region and at comparable and representative reference areas outside of MPAs. We utilized small (19 and 22 ft) vessels for these surveys since representative reef habitats in this region are often remote and inaccessible from shore. These habitats are better represented in this study relative to those often reported on from the limited beach access surveys confined to small areas by other monitoring efforts. We used SCUBA surveys to measure the physical characteristics of rocky reefs and the relative abundance and sizes of many of the fishes, mobile and sessile invertebrates, and algae at each site. Species abundances were estimated along 30 m long swath surveys that count individuals within a 60 m² area or at predetermined points along a transect using uniform point contact (UPC) methods to estimate the percent cover of colonial and encrusting organisms covering the reefs.

ROV Surveys of the Mid-depth and Deep Subtidal Ecosystems, California North Coast MPA Baseline Study, 2014 to 2015

Marine Applied Research and Exploration (MARE) preformed quantitative baseline surveys within the NCSR in 2014 and 2015 with the overall goal to describe the condition of three distinctive priority ecosystem features within four MPAs and their adjacent reference study areas: a) mid-depth rock ecosystems, b) softbottom subtidal ecosystems, and c) deep ecosystems (including canyons). Long-term monitoring trends within these habitats will be compared to baseline conditions, assisting in evaluating MPA effectiveness. The four MPAs chosen for evaluation include: Point St. George Reef Offshore SMCA, Reading Rock State Marine Reserve, Mattole Canyon State Marine Reserve and Ten Mile State Marine Reserve. Outside reference areas with similar habitats and depths were also surveyed for comparison. During the first two years following implementation, benthic visual surveys were conducted using a remotely operated vehicle (ROV) to assess initial changes in fishes, macro-invertebrates and associated seafloor habitats. The ROV collected video and still imagery while moving along a fixed path (transect) along the sea floor. Video imagery collected was analyzed to characterize substrate, habitat types, habitat complexity (rugosity), and estimate finfish and macro-invertebrate distribution, relative abundance and density. In total, 60 ROV dives were completed surveying more than 106 km (19 ha) between 13 and 421 m deep. In addition, over 16,500 still photos were taken.

Characterization of Sandy Beaches and Adjacent Surf Zones, California North Coast MPA Baseline Study, 2014 to 2015

We combined taxonomically detailed surveys of macroinvertebrates and birds with targeted sampling of regionally important focal taxa including surf zone fishes, kelp and sand crabs; physical and biological metrics of the habitat; and activities of people on the beaches to develop an integrated understanding of the important ecosystem processes structuring northern California beaches. Our baseline study program consisted of the following components: 

Nine monthly surveys (from September 2014 through May 2015) of birds, macrophyte wrack (detached marine vegetation such as seaweeds, surfgrasses and seagrasses that are deposited on the beach), human use and physical characteristics of 12 sandy beaches and their adjacent surf zones (6 MPA and 6 reference sites);

A one-time, comprehensive survey of intertidal invertebrate biodiversity during summer 2014 of the 12 focal sandy beaches;

A comprehensive baseline survey of redtail surfperch (Amphistichus rhodoterus), including diet analysis, at nine sandy beaches (4 MPA, 5 reference sites) over two years;

Targeted monthly surveys of sand crabs (Emerita analoga) done concurrently with redtail surfperch surveys on three long beaches for three months; and

Sampling of night smelt (Spirinchus starksi) spawning aggregations from nine beaches (5 MPA, 4 reference) during spring and summer over two years.
