Stream chemistry concentrations and fluxes using proportional sampling in the Andrews Experimental Forest, 1968 to present
Stream chemistry sampling and analysis was initiated at the H.J. Andrews Experimental Forest in 1968 in two small watersheds (Watersheds 9,10). Sampling has expanded as additional paired watershed studies (Watersheds 1, 2, 6, 7, 8) and monitoring (Mack, Lookout Cr) were initiated over time. Water samples are collected proportionally to streamflow as a function of stage height and composited at each stream gauging site. Composite sample periods are generally three weeks and 3 one-week samples are commonly composited in the lab before analysis. Water samples are analyzed at the Cooperative Chemical Analytical Lab (CCAL) (http://www.ccal.oregonstate.edu/ ). Concentrations of analytes include dissolved and particulate nitrogen, phosphorus, carbon, as well pH, conductivity, suspended sediment, and full suite of cations and anions. Monthly and annual mean concentrations are calculated by weighting 3-week periods by streamflow. Fluxes are calculated using concentrations and flow. The original objective was to examine the nutrient budgets for small watersheds and to evaluate changes in average concentrations and fluxes following timber harvest in comparison with unharvested reference watersheds. This study is conducted in conjunction with Andrew's precipitation chemistry (CP002) and the U.S. National Atmospheric Deposition Program (NADP).
Precipitation and dry deposition chemistry concentrations and fluxes, Andrews Experimental Forest, 1969 to present
Collection and analyses of precipitation chemistry were initiated in 1969 at the low-elevation Primary Met site, and in 1973 at a mid-elevation Hi-15 site. Rain collection samples accumulate from one week to three weeks in bulk and NADP type collectors and then are transported to Cooperative Chemical Analytical Laboratory (CCAL) for analysis. Analytes include nitrogen, phosphorus, carbon, and cations and anions as well as pH, conductivity, alkalinity and particulate sediment. Concentration and volume of precipitation are combined for inflow. Dry deposition chemistry concentrations began in 1989 and are analyzed 2-4 times per year at one site. The original objectives were to evaluate precipitation chemistry inputs versus chemistry outputs in streamflow from forested watersheds. The study has evolved into a general monitoring effort for precipitation chemistry that is among the least contaminated of any within the USA. This study is conducted in conjunction with Andrews streamflow chemistry (CF002) and the U.S. National Atmospheric Deposition Program (NADP).
Stream discharge and bedload accumulation in gauged watersheds at the South Umpqua Experimental Forest, Coyote Creek, 1963 to 1981 and 2001 to present
Stream discharge is collected on four small watersheds in the Coyote Creek drainage within the South Umpqua Experimental forest in the southwest Oregon Cascades. Stream discharge data was started in October 1963 and discontinued in June 1981 (discontinued April 1985 on Watershed 4). Stream discharge measurement was resumed in December 2000 on all four watersheds. Watersheds 1, 2, and 3 were harvested with differing silvicultural methods in summer 1971, and watershed 4 is the control. High resolution temporal data is provided as well as daily, monthly and annual summary data. Streamflow data by sampling intervals are also provided from 1970 to 1981 when stream water chemistry data were being collected. Annual bedload accumulation totals from each of the four watersheds is also provided beginning 2001.
Aquatic vertebrate populations in streams throughout the HJ Andrews Experimental Forest, 2013 to present
This multi-year study quantifies the distribution and density of aquatic vertebrates throughout Lookout Creek stream network, including Mack, McRae and Upper Lookout Creeks. We are examining how predictable and consistent the densities and sizes of cutthroat trout and coastal giant salamanders are throughout the network and whether they fluctuate synchronously with vertebrates sizes and densities in Mack Creek that have been measured since 1987 (AS006). We are also examining biomass and condition of individuals across sites. Density and developmental stage of coastal tailed frog tadpoles are noted. We use electroshocking in discrete blocked reaches (depletion and mark-recapture methodologies) to collect individuals that are then weighed, measured and released. Site specific characteristics are measured at each sampling event, including wetted widths and water depths. Broader landscape metrics, including stream gradient and watershed area, were calculated for sites.
Baltimore Ecosystem Study: Soil moisture and temperature along an urban to rural gradient, 2011 - present
Soil temperature and soil moisture have been measured at multiple locations in and around Baltimore Maryland to provide data on these variables in forests and lawns across an urban to rural gradient. In July 2011, we installed one Decagon Em50 Datalogger with five 5TM VWC/Temperature probes at four established forested, upslope, 20 x 20-m plots, two rural (ORU1, ORU2) and two urban (LEA1, LEA2), at 2 forested riparian sites at two transects along a stream (ORUR, ORLR), and two lawn plots on the campus of the University of Maryland Baltimore County campus (UMBC1, UMBC 2). Probes were buried horizontally at 10cm depth (except UMBC1 and UMBC2 where the five probes are mounted horizontally at a single location at depths of 50, 40, 30, 20 and 10 cm depth). At the upslope forested plots, the five probes are replicates. At the two riparian sites, probes are deployed in either "hummocks (drier, higher)" or in "hollows (lower, wetter)". Soil temperature and soil moisture were measured at hourly intervals on these plots beginning in July 2011. In March 2017, an additional data logger was installed at Hillsdale Park (HD1) in a forested urban area. The five probes at HD1 were buried horizontally at 10cm depth and are replicates. Earlier soil moisture data were collected monthly (1999-2011), and can be found in https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-bes&identifier=417

Sediment Elevation Change (Feldspar Marker Horizon Method) from Northeastern Florida Bay (FCE) from 1996 to Present
The long term goal of the South Florida Water Management District's research program focuses on the following central objective: Regional processes mediated by water flow control population and ecosystem level dynamics at any location within the coastal Everglades landscape. This phenomenon is best exemplified in the dynamics of an estuarine oligohaline zone where fresh water draining phosphorus-limited Everglades marshes mixes with water from the more nitrogen-limited coastal ocean. Data in this data package are specifically to monitor soil elevation change relative to current sea level.

Forest Inventory of a Northern Hardwood Forest: Bird Area, 1991 - present, Hubbard Brook Experimental Forest
The forest inventory surveys in the bird area were initiated in 1981 and transects were made permanent in 1991 by Tom Siccama who created and designed this tree survey. The inventory is representative of approximately 2.5 km2 of mid elevation northern hardwood forest. The data set is particularly geared toward producing accurate mortality and recruitment estimates. It consists of a total inventory of all trees greater than or equal to 10 cm dbh within each of four 10 m wide belt transects. The parallel transects are placed approximately 200 m apart and 290° bearing in an east-west direction for 2200 to 2900 m. In 1991, each live stem greater than or equal to 10 cm dbh was tagged with a unique number. Tree vigor is assessed every two years and diameter is remeasured every ten years. Every two years, new tags are placed on stems that have grown into the 10 cm diameter class. This dataset includes 1991 and subsequent samplings. These detailed tree status data provide a high resolution assessment of tree vital rates, particularly recruitment and mortality rates. The data show an increase in both mortality and recruitment over the 30 year measure time (1991-2021). The number of unhealthy trees has also increased to about 8% of the live trees. The measure period includes notable disturbances, particularly the 2013 microburst impacted the west end of lines 5 and 9, and a saddled prominent outbreak concurrent with drought conditions in 2020. Data from an earlier sampling in 1981 (pre-tagging of individual trees) can be found in: Sherry, T., D. Holmes, and T. Siccama. 2019.
