title: Long-term trends in abundance of Lepidoptera larvae at Hubbard Brook Experimental Forest and three additional northern hardwood forest sites, 1986-2018

description: Numbers and lengths of Lepidoptera larvae (caterpillars, all species)
 were censused on shrub level foliage at biweekly intervals from late
 May/early June through late July/early August each year. Measurements
 were conducted on the Main bird plot in the Hubbard Brook Experimental
 Forest and on three additional plots within the White Mountain
 National Forest from 1986-1997..

title: Physical, chemical, and metabolic leaf characteristics within sugar maple in the MELNHE study at Bartlett Experimental Forest, central NH USA, 2017

description: The MELNHE study looks at patterns of resource limitation through
 nutrient manipulations in three study sites in New Hampshire: Bartlett
 Experimental Forest, Hubbard Brook Experimental Forest, and Jeffers
 Brook, located in the White Mountain National Forest. The
 investigation is monitoring stem diameter, leaf area, sap flow, foliar
 chemistry, leaf litter production and chemistry, foliar nutrient
 resorption, root biomass and production, mycorrhizal associations,
 soil respiration, heterotrophic respiration, N and P availability, N
 mineralization, soil phosphatase activity, soil carbon and nitrogen,
 nutrient uptake capacity of roots, and mineral weathering.
 Applications of N and P began in June 2011 and continue at the rate of
 30 kg N/ha/yr (as NH4NO3) and 10 kg P/ha/yr (as NaH2PO4).

 
 This data set includes physical, chemical, and metabolic leaf
 characteristics collected in a vertical transect within individual
 tree crowns. Because trees varied in crown depth, not all trees have
 the same number of samples collected. Depth from the top of the crown
 was measured and climbing ropes and a pole pruner were used to collect
 a population of leaves.

title: Hubbard Brook Experimental Forest: Instantaneous Streamflow by Watershed, 1956 – present

description: Streamflow at 9 watersheds (12-77 Hectares) within the Hubbard Brook
 Experimental Forest was measured continuously from as early as 1955.
 Streams were gaged with V-notch weirs and rectangular San Dimas flumes
 at the outlet of each watershed. Through 2012, stage heights were
 recorded by means of a float attached mechanically to a pen on a
 spring-wound strip-chart recorder. Beginning January 1, 2013 the
 charts were replaced with digital sensors.

title: Hubbard Brook Experimental Forest (US Forest Service): Total Daily Precipitation by Watershed, 1956 - present

description: Watershed precipitation is estimated using the Thiessen
 Means weighting method. Daily watershed precipitation values
 are a weighted average of daily precipitation from standard
 gages in or near the watershed. The weighting factor for each
 gage is the fraction of the watershed area nearest that
 gage.

title: Hubbard Brook Experimental Forest (USDA Forest Service): Daily Streamflow by Watershed, 1956 - present

description: Streamflow at 9 watersheds within the Hubbard Brook
 Experimental Forest has been measured continuously from as
 early as 1955. Streams are gaged with V-notch weirs at the
 outlet of each watershed. Height of water behind the weir
 increases with increased streamflow and is recorded by means
 of a float attached mechanically to a pen on a spring-wound
 strip-chart recorder. Gage height is converted to streamflow
 rate by calibration factors and then integrated to generate
 daily streamflow. Streamflow rate is measured as volume per
 unit time(L/s) and is proportional to the watershed
 area.
 Beginning January 1, 2013, instantaneous streamflow
 data (and derived daily streamflow) are measured by
 electronic sensors, and data are provisional as the
 transition from chart to digital data collection is still
 under evaluation. Data may be updated before they are
 finalized. Please contact the dataset creator prior to data
 use/publication. Daily streamflow data are derived from the
 instantaneous streamflow record, and additional information
 (quality control flagging and gapfilling) can be found in
 that record

title: Hubbard Brook Experimental Forest: Soil-atmosphere fluxes of carbon dioxide, nitrous oxide and methane on snow removal plots

description: Soil atmosphere fluxes of the trace gases; carbon dioxide (CO2),
 nitrous oxide (N2O) and methane (CH4) have been measured at several
 locations at the Hubbard Brook Experimental Forest (HBEF) including 1)
 the “freeze” study reference plots that provide contrast between
 stands dominated (80%) by sugar maple versus yellow birch and low and
 high elevation areas, 2) the Bear Brook Watershed where trace gas
 sampling is coordinated with long-term monitoring of microbial biomass
 and activity and 3) watershed 1 where trace gas sampling locations
 were co-located with long-term microbial biomass and activity
 monitoring sites that are located near a subset of the lysimeter sites
 established for the calcium addition study on this watershed. This
 dataset contains the Freeze study data. Watershed 1 and Bear Brook
 trace gas data can be found in:

title: Soil moisture and temperature along an elevation gradient at the Hubbard Brook Experimental Forest, 2010 - present.

description: Soil temperature and soil moisture have been measured
 at multiple locations at the Hubbard Brook Experimental
 Forest (HBEF), as part of a study of the relationships
 between snow depth, soil freezing and nutrient cycling
 (http://www.ecostudies.org/people_sci_groffman_snow_summary.html). 
 In October 2010, we established 6, 20 x 20-m plots (intensive
 plots) and 14 10 x 10-m plots (extensive plots) along an
 elevation gradient, with eight of the plots on north-facing
 slopes and twelve on south-facing slopes. Soil temperature
 and soil moisture were measured at hourly intervals on these
 plots beginning in November 2010. Six locations were
 discontinued in September 2012 (E04, E05, E06, E11-B, E13,
 and E14).

title: Measurements of microbial biomass and activity in two snow manipulation experiments at Hubbard Brook Experimental Forest 1998 – 2004

description: In 1997, as part of a study of the relationships between snow depth,
 soil freezing and nutrient cycling
 (http://www.ecostudies.org/people_sci_groffman_snow_summary.html), we
 established eight 10 x 10-m plots located within four stands; two
 dominated (80%) by sugar maple and two dominated by yellow birch, with
 one snow reduction (freeze) and one reference plot in each stand. In
 2001, we established eight new 10-m x 10-m plots (4 treatment, 4
 reference) in four new sites; two high elevation, north facing and two
 low elevation, south facing maple-beech-birch stands. To establish
 plots for the “freeze” study, we cleared minor amounts of understory
 vegetation from all (both freeze and reference) plots (to facilitate
 shoveling). We then installed soil solution samplers (zero tension
 lysimeters), thermistors for soil temperature monitoring, water
 content (time domain) reflectometers (for measuring soil moisture),
 soil atmosphere sampling probes, minirhizotron access tubes, and trace
 gas flux measurement chambers (described below). All plots were
 equipped with dataloggers to allow for continuous monitoring of soil
 moisture and temperature. Treatments (keep plots snow free by
 shoveling through the end of January) were applied in the winters of
 1997/98, 1998/99, 2002/2003 and 2003/2004. Measurements of soil
 nitrate (NO3
 -) and
 ammonium (NH4
 +)
 concentrations, microbial biomass carbon (C) and nitrogen (N) content,
 microbial respiration, potential nitrification and N mineralization
 rates, pH, and denitrification potential were measured on these plots
 at multiple time points during these studies.

title: Long-term measurements of microbial biomass and activity at the Hubbard Brook Experimental Forest, 1994 - present

description: Long-term monitoring of soil nitrate (NO3-) and
 ammonium (NH4+) concentrations, microbial biomass carbon (C)
 and nitrogen (N) content, microbial respiration, potential
 nitrification and N mineralization rates, and denitrification
 potential has been ongoing at the Hubbard Brook Experimental
 Forest since 1994. Samples have been collected in the Bear
 Brook Watershed (west of Watershed 6) beginning in 1994. In
 1998, our sampling regime was extended to Watershed 1 in an
 effort to monitor and quantify microbial response to a
 whole-watershed calcium addition.

title: MELNHE: Foliar Chemistry 2008-2016 in Bartlett, Hubbard Brook, and Jeffers Brook (12 stands)

description: We are conducting nutrient manipulations in three study sites in the
 White Mountain National Forest in New Hampshire: Bartlett Experimental
 Forest, Hubbard Brook Experimental Forest, and Jeffers Brook.

 
 We monitored foliar chemistry in 12 of our stands (excluding C3)
 pre-treatment (2008-2010) and post-treatment (2014-2016). In general,
 we found that foliar N concentrations were higher with N addition and
 foliar P concentrations were higher with P addition. More
 interestingly, P addition reduced foliar N concentrations and N
 addition reduced foliar P concentrations. Some interactive effects
 were observed (i.e. NxP, Species x N, Species x P, Species x N x P).

 
 This dataset contains pre- and post- treatment foliar chemistry data,
 and data from the analysis of quality control standard samples.

title: Climate Change Across Seasons Experiment (CCASE) at the Hubbard Brook Experimental Forest: Soil Water Isotopic Composition

description: Natural abundance stable isotopes of oxygen and hydrogen in soil water
 were measured adjacent to the Climate Change Across Seasons Experiment
 (CCASE) plots. There are six plots total (each 11 x 14 m). Two are
 warmed 5 degrees C throughout the growing season (Plots 3 and 4). Two
 others are warmed 5 degrees C in the growing season and have snow
 removed during winter to induce soil freezing and then warming cables
 turn on to create thaws; each soil freeze/thaw cycle includes 72-hours
 of soil freezing followed by 72-hours of thaw (Plots 5 and 6). Four
 kilometers (2.5 mi) of heating cable are buried in the soil to warm
 these four plots. Two additional plots serve as controls for our
 experiment (Plots 1 and 2). This data set includes natural abundance
 stable isotopes of oxygen and hydrogen in soil water from 2018.
