Triton: Survivability Enhancement of a Multi-Mode Point Absorber

Tim Mundon & Brian Rosenberg
This submission includes final project deliverables for DE-FOA-0001310. The overall goal of the project was to design and validate a survival mode for the Triton WEC that allows for a reduction in peak loads, while simultaneously allowing for a reduction of capital cost due to the elimination of overdesign to account for uncertainty. In addition, the project sought to carefully understand performance of the design without survival mode engaged under extreme wave conditions so as...

SPRUCE Peat Physical and Chemical Characteristics from Experimental Plot Cores, 2012

C. Iversen, P. Hanson, D. Brice, J. Phillips, K. McFarlane, E. Hobbie & R. Kolka
This data set reports the results of physical and chemical analyses of peat core samples from the SPRUCE experimental study plots located in the S1-Bog. On August 13-15, 2012, a team of SPRUCE investigators and collaborators collected core samples of peat in the SPRUCE experimental plots. The goal was to characterize the biological, physical, and chemical characteristics of peat, and how those characteristics changed throughout the depth profile of the bog, prior to the initialization...

SPRUCE Stability of Peatland Carbon to Rising Temperatures: Supporting Data

R. Wilson, A. Hopple, M. Tfaily, S. Sebestyen, C. Schadt, L. Pfeifer-Meister, C. Medvedeff, K McFarlane, J. Kostka, M Kolton, R. Kolka & L. Kluber
This data set reports the results of extensive field measurements and laboratory analyses of samples from the SPRUCE experiment. Results indicate that ecosystem-scale warming of over 2 m of peat exponentially increased CH4 emissions —but not ecosystem respiration of CO2. Multiple lines of evidence, including incubations and in situ analyses of 14C, dissolved gases, and microbial community metabolic potential, indicate that CH4 emissions increased due to surface processes and not degradation of deeper buried carbon....

Modelica IBPSA Library v1

Michael Wetter, David Blum & Jianjun Hu
The Modelica IBPSA library is a free open-source library with basic models that codify best practices for the implementation of models for building and community energy and control systems. The development of the IBPSA library is organized through the IBPSA Project 1 (https://ibpsa.github.io/project1) of the International Building Performance Simulation Association (IBPSA). This library is typically not used directly by end-users. Rather, it is integrated by developers of other Modelica libraries for building and community energy...
