Daily summary of 10 cm soil temperatures in the Arctic LTER moist acidic experimental plots from 1998 to present, Toolik Lake Field Station, Alaska.
Daily summary of 10 cm soil temperatures in the Arctic LTER moist acidic experimental plots for the control (CT), greenhouse (GH), greenhouse plus nitrogen and phosphorus (GHNP) and nitrogen and phosphorus (NP) plots. Soil temperature probes in the tundra soil were problematic with frost heaving causing the depth of measurements to change. In order to provide a consistent year to year temperature record notes on changes in depths were used to select the temperature sensor that was within + or – 3 cm of the 10 cm and then averaged daily.
Pharmaceutical effects on biofilm functioning quantified via contaminant exposure substrates presented in Rosi et al. 2018.
An ongoing component of the Baltimore urban long-term ecological research (LTER) project (Baltimore Ecosystem Study, BES) is the use of the watershed approach and monitoring of stream water quality to evaluate the impacts of multiple chemical stressors on urban stream ecosystem functioning within Baltimore. The LTER research has focused on the Gwynns Falls watershed, which spans a gradient from highly urban, urban-residential, and suburban zones. In addition, a forested watershed serves as a reference. The long-term sampling network includes four longitudinal sampling sites along the Gwynns Falls mainstem, as well as several small (40-100 ha) watershed within or near the Gwynns Falls, providing data on water quality in different land use zones of the watersheds. Each study site is continuously monitored for discharge and is sampled weekly for water chemistry. Those data are available elsewhere on the BES website. We are interested in studying the effects of pharmaceuticals and personal care products (PPCPs) on stream biofilm functioning within urban streams. We constructed and deployed contaminant exposure substrates (CES) in four streams within the greater Baltimore, Maryland, USA area to measure the responses of biofilms in each of the four streams to caffeine, ciprofloxacin, cimetidine, diphenhydramine, and no PPCPs. We incubated CES for 2 weeks in the four different streams, with five replicate CES for each treatment being randomly placed on plastic L-bars within each stream. After the two-week deployment, we used the light-dark incubation approach to estimate gross primary production and community respiration via change in dissolved oxygen (DO) for biofilms colonizing substrates (either cellulose sponges to select heterotrophic biofilms or fritted glass disks to select for autotrophic biofilms) topping each CES. This dataset includes all of the raw data for the light-dark incubations used to calculate gross primary production and community respiration for the v
Foliar Ca, Sr and 87Sr/86Sr measurements on Watershed 1 at the Hubbard Brook Experimental Forest, 1999 - present
This dataset includes ICP-OES analyses of Ca and Sr concentration and thermal ionization mass spectrometry analyses of 87Sr/86Sr ratios for annual samples of Watershed 1 understory foliage. Additional foliar elements were analysed and are included in the data table. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
Chemistry of Bulk Precipitation at Hubbard Brook Experimental Forest, 1969 - present, Robert S. Pierce Ecosystem Laboratory Facility
Precipitation chemistry has been measured at the Hubbard Brook Experimental Forest since 1963. This data set includes volume-weighted, average, monthly concentrations of cations, anions, and pH. Monthly averages are calculated from samples collected at weekly intervals from HBEF Raingage 22 (RG-22), adjacent to the Robert S. Pierce Ecosystem Laboratory. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
