Background: The range of sites within the LTER network provides an excellent opportunity to understand aquatic and soil OM (organic matter) dynamics in diverse ecosystems in order to develop overarching hypotheses about OM dynamics on a larger scale in the context of the global carbon cycle. Dissolved organic material (DOM) is a major pool of… Read more »

Coastal Wetland Ecology and Geomorphology
Goals. I propose a working group on coastal wetland ecology and geomorphology that will meet four times before April 2013 to develop and submit a Macrosystems Biology proposal to NSF. This working group proposal grew out of a working group (Modeling Wetland Processes) organized by S. Pennings and A. Burd at the 2012 LTER ASM,… Read more »
Quantifying Uncertainty in Wet Atmospheric Deposition
BACKGROUND Monitoring nutrients in precipitation inputs and other ecosystem fluxes has advanced our understanding of biogeochemical cycling. However, uncertainty due to variability or error in observations and models has rarely been reported in ecosystem studies. This makes it difficult to determine rates of change over time or compare results across multiple sites with quantitative confidence. … Read more »
Synthesizing long-term records and eco-hydrologic modeling to quantify structural legacy effects
Rationale: While the importance of legacy effect characterization to interpreting long-term records of ecological conditions has continued to emerge (Bain et al. in review “Legacies in Material Flux: Structural Catchment Changes Pre-date Long-term Studies” BioScience) some early structural legacies (e.g. substantial soil losses to erosion) are challenging to characterize with controlled experiments. However, the extended… Read more »
SiteDB redesign to accommodate ClimDB/HydroDB and StreamChemDB
Summary: This proposed workshop will review the current design of SiteDB and recommend design changes to facilitate the integration of value-added databases, ClimDB/HydroDB and StreamChemDB, into the Network Information System (NIS). The work will focus on the redesign of SiteDB and the development of an EML template to accommodate descriptive metadata from these value-added databases.
EML Diagnosis and Best Practice Implementation Mentor
Summary: Of the EML datasets being contributed to the LTER NIS, a significant fraction is not of sufficient quality for automated use, and a variety of approaches will be necessary to remedy this. The EML Congruence Checker (ECC) is being developed to report on dataset usability, but experience indicates that simply informing sites of dataset… Read more »
Integrating Local Knowledge into Long Term Ecological Research – MALS Training and Planning Workshop
Objective: Convene a three-day training/planning workshop in Spring 2012 that provides LTER investigators, LTER graduate students, and others with a theoretical orientation, practical skills, and the research tools to document local ecological knowledge and integrate that knowledge with spatial analysis and other forms of scientific data to understand social-ecological resilience
LTER Personnel Database Web Services Development
Allow site IMs to manage their personnel records through a single interface provided by LNO and then redisplay that content on their own websites by incorporating a web service call within a small web application designed to work at their own site. Allow site IMs to develop automated methods to populate or update their own… Read more »
Tools and training for sensor network establishment and management
Abstract There is strong interest among LTER sites in the establishment and management of sensor networks and there is a need for coordinated training and tool sharing. Coincidentally, NCEAS is planning a training workshop on sensor tools within the Real-time Environment for Analytical Processing (REAP) project context. We propose a single LTER/NCEAS cost-shared training that… Read more »
Acquisition and management of data from remote locations
Background: The Sevilleta LTER possesses a large network of diverse research sites, weather stations, and webcams interconnected by a wireless network that can be remotely accessed by researchers around the world. Presently, there are approximately thirty networked research sites comprising of over fifty dataloggers, thousands of sensors, and several webcams distributed over more than 100… Read more »
