Dissolved inorganic nutrients from NES-LTER cruises, including 4 macro-nutrients from water column bottle samples, ongoing since 2006

Northeast U.S. Shelf LTER & Heidi Sosik
Dissolved inorganic nutrients are measured from water column bottle samples taken on NES-LTER cruises (ongoing since 2006) and include nitrate + nitrite, ammonium, silicate, and phosphate. For years 2006 - 2017 prior to the start of the NES-LTER project, sampling was usually in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO). Sampling frequency near MVCO is approximately monthly. Samples were filtered, frozen, then processed at the Woods Hole Oceanographic Institution's Nutrient Analytical Facility. Each...

CSA02 Soil Macroarthropod Densities and Biomass on annually burned and unburned watersheds

John Blair
Belowground densities and biomass of macroarthropods on annually were measured by hand-sorting techniques. Total herbivore biomass was greater in soils of annually burned sites, and was composed largely of white grubs (Scarabaeidae).

McMurdo Dry Valleys Particulate Organic Carbon and Nitrogen Concentrations in Lakes

John Priscu
An important part of the McMurdo Long Term Ecological Research (LTER) is evaluating carbon and nitrogen budgets in perennial ice-covered lakes. This dataset addresses this core area of research and quantifies the particulate carbon and nitrogen found at specific depths in McMurdo Dry Valley lakes.

Soil solution chemistry data from long-term study plots

Baltimore Ecosystem Study Long-Term Study Plot Soil Metadata Participants Peter Groffman, Cary Institute of Ecosystem Studies Richard V. Pouyat, U.S. Forest Service Lisa Martel, Cary Institute Of Ecosystem Studies Introduction The Baltimore Ecosystem Study (BES) has established a network of long-term permanent biogeochemical study plots. These plots will provide long-term data on vegetation, soil and hydrologic processes in the key ecosystem types within the urban ecosystem. The current network of study plots includes eight forest...

Carbon quality regulates the temperature dependence of aquatic ecosystem respiration

Stephen F Jane & Kevin C Rose
Lakes are undergoing a variety of changes that may alter their role in the global carbon cycle. Lake temperatures are increasing at the same time that lakes in many regions are experiencing long-term increases in dissolved organic carbon (DOC) concentrations. The balance between rates of ecosystem respiration (ER) and gross primary production (GPP) is an important determinant of CO2 outgassing from lakes and thus it is important to understand factors regulating ER rates in these...

Eight Mile Lake Research Watershed, Carbon in Permafrost Experimental Heating and Drying Research (DryPEHR): Growing season NDVI from the DryPEHR project, Healy AK, 2011-2017

Anthony J Garnello, Meghan Taylor, Susan M.N. Natali, Edward A.G. Schuur, Verity G. Salmon & Bonanza Creek LTER
This drying and warming experiment addresses the following questions: 1) Does ecosystem drying, warming and permafrost thaw cause a net release or uptake of C from the ecosystem to the atmosphere?, 2) Does the decomposition of old C that comprises the bulk of the soil C pool influence ecosystem C loss? 3) How do drying and warmign affect plant communities and ecosystem properties? We are answering these questions using a combined warming and drying experiment...
