Santa Barbara Coastal site, station Santa Cruz Island, Twin Harbor West, Santa Barbara Channel, study of animal density of Medialuna californiensis in units of numberPerMeterSquared on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Santa Barbara Coastal (SBC) contains animal density of Medialuna californiensis measurements in numberPerMeterSquared units and were aggregated to a yearly timescale.

Santa Barbara Channel fish surveys at deep reefs: Footprint, Piggy Bank, Anacapa Passage

The dataset contains fish surveys from deep natural reefs in the northern Santa Barbara Channel Islands, Southern California, mainly at reefs named Piggy Bank, Footprint (local names) and Anacapa Passage. Data collection began in 1995. Reefs are located at depths between 30 and 360 m (100 and 1,180 feet). Sampling was by the manned submersibles Delta and DualDeepworker and an unmanned Remotely Operated Vehicle (ROV). These sites included a wide range of such habitats as banks, ridges, and carbonate reefs, ranging in size from a few kilometers in length to less than a hectare in area. On these features, we focused on hard bottom macrohabitats, including kelp beds, boulder and cobble fields, and bedrock outcrops. Transects were not deliberately revisited; some reefs were surveyed as many as four times per year. All transects are 2 m wide; transect length varied (see data). The dataset includes two tables: (1) the fish counts at Piggy Bank, Footprint, and Anacapa Passage; and (2), the habitat associated with each of the survey segments. Fishes were identified to lowest possible taxon (usually species), and verified against the WoRMs database (http://www.marinespecies.org/).

Santa Barbara Channel fish and invertebrate surveys at oil and gas platforms

Dataset contains occurrences of fish and invertebrates at nine oil and gas platforms between 1995 and 2011 in the southern California (Pt. Arguello to Long Beach). Observations were collected using a manned submersible at depths ranging from 29 – 224 meters (95 - 739 feet). Data are organized into two tables: (1) the fish count (1995-2000) and (2) the invertebrate count (1997-2011). Fish surveys were conducted primarily at nine Platforms (Irene, Hidalgo, Harvest, Hermosa, Holly, Gilda, Grace, Gina, Gail) in the Santa Barbara Channel and Santa Maria Basin. Invertebrate surveys were collected at these nine platforms plus Platform Edith, located off Long Beach (1998) and partial submersible surveys were completed around Platforms C, B, A, Hillhouse, Henry, Houchin, Hogan, and Habitat (2000). See additional methods under “Methods” and citations therein. The Santa Barbara Channel and Santa Maria Basin are situated in a dynamic marine transition zone between the regional flow patterns of central and southern California. The Santa Barbara Channel is about 100 km long by about 50 km wide (60 x 20 miles) and is bordered on the south by the Northern Channel Islands (San Miguel, Santa Rosa, Santa Cruz, and Anacapa). The smaller Santa Maria Basin is located off Pt. Arguello to the northwest. The entire area is bathed in a complex hydrographic system of currents and water masses. The convergence of different water masses in the Santa Barbara Channel results in relatively large scale fluctuations in physical parameters (e.g., temperature, salinity, oxygen, and nutrient concentrations) and biotic assemblages (e. g., flora and fauna).

Santa Barbara Channel fish surveys at shallow outcrops

Nine nearshore, shallow-water rock outcrops, seven along the mainland and two off Anacapa Island, were monitored annually from 1995 to 2000. All locations were surveyed using scuba, and belt transects was were conducted at each site. These natural outcrops are geographically distributed across the Santa Barbara Channel providing opportunities for spatial and temporal comparisons between natural reef and oil/gas platforms. Fish surveys at platforms were conducted using scuba within a few days of these surveys at rock outcrops; the data can be viewed at: https://portal.lternet.edu/nis/mapbrowse?scope=edi&identifier=113 This scuba project was conducted and reported under a cooperative agreement (Agreement 1445-CA09-95-0836) between the U. S. Geological Survey (Biological Resources Division) and the University of California, Santa Barbara. Citation of report: Love, M. S., D. M. Schroeder, and M. M. Nishimoto. 2003.

Santa Barbara Channel fish surveys at shallow regions of oil and gas platforms (SCUBA)

This dataset included fish counts that were surveyed in the shallow sections (0 – 40 meters) of the oil and gas platforms using Scuba. The oil and gas platforms are located in the Santa Barbara Channel, California, USA. Each of the eleven platforms (GILDA, GINA, HOLLY, IRENE, HERMOSA, HIDALGO, GAIL, GRACE, HARVEST, C, and HENRY) were surveyed multiple times a year from 1995 to 2000. This scuba project was conducted and reported under a cooperative agreement (Agreement 1445-CA09-95-0836) between the U. S.

McMurdo Dry Valley Relict Channel Locations

INVERTEBRATE TAXA QUALITATIVE ABUNDANCES IN REACTIVATED CHANNEL

Algal Abundances in Reactivated Channel

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the percent of total biomass (abundance) represented by algal type (brown, red, orange or green), phylum, species and morphotype for the Relict Channel in the Fryxell basin.

Algae Ash-Free Dry Mass in Reactivated Channel

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the ash-free dry mass represented by algal type (brown-colored, red-colored, orange-colored, or green-colored, filamentous, sand, rock or moss) and incubation type (light, dark, or none) for the Relict Channel in the Fryxell basin.

Algae Primary Productivity in Reactivated Channel

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This data set includes results from light and dark incubations of algae to calculate net and gross primary productivity of algal communities from the Relict Channel in the Fryxell basin.

Algal and Moss Biomass in Reactivated Channel

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, water was diverted to a relict stream channel in order to reactivate the streamflow. The purpose of this experiment was to quantify the time scales of response to the arrival of water after many years of dessication. This table contains data showing the chlorophyll, carbon, nitrogen, and hydrogen concentrations of algal communities and some mosses from the relict channel. The data constitutes the reactivated channel's algal and moss biomass data, along with measurements of the amount of carbon and nitrogen associated with algal mats for construction of nutrient budgets.
