Abstract:
This dataset contains snow depth and frost depth measurements from the Climate Change Across Seasons Experiment (CCASE) at the Hubbard Brook Experimental Forest. Samples are collected weekly throughout the winter months. 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.

Description:
RESEARCH SUMMARY Mean annual temperatures for the northeastern U.S. are projected to increase 3-5 degrees C by the year 2100, which could increase water and nutrient uptake and carbon storage by trees. However, the increase in temperature will lead to a smaller winter snowpack and increased frequency of soil freeze/thaw cycles, which may offset the positive effects of warming by damaging roots. The overall result could be reduced nutrient uptake and storage of carbon and further elevation of atmospheric CO2 concentrations. Understanding the mechanisms and controls underlying changes in nutrient uptake by trees is necessary for improving predictions of how ecosystems will respond as the climate changes. Whereas many studies have evaluated the impacts of climate change on forests within a single season, few have examined the impacts of climate change across seasons and how these impacts interact. These "across season" effects could be antagonistic or synergistic, which would not be apparent from examining one season alone. The goals of this research are to determine the interactive effects of winter and growing season climate on water and nutrient uptake and carbon sequestration in northern hardwood forests. These goals are being accomplished with a new ecosystem warming experiment at Hubbard Brook. SITE DESCRIPTION CCASE was established in a red maple (Acer rubrum) dominated forest in 2012. There are six plots total (each 11 x 14m). 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 freeze/thaw cycles (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). FIELD COLLECTION PROCEDURES Snow depth is measured weekly in four locations in each plot from December through April using a meter stick placed vertically into the snowpack on each sample date in each plot quadrant. Soil frost depth is measured weekly using frost tubes constructed of flexible PVC tubing (1.3 cm diameter) filled with methylene blue dye (Ricard et al. 1976), which were inserted into rigid PVC casings 50 cm below the soil surface at four locations within each plot.
