Radiocarbon ages, whole-rock geochemical data, and pumice density measurements for the Sacarosa tephra-fall deposit, Misti volcano, southern Peru Radiocarbon ages, whole-rock geochemical data, and pumice density measurements for the Sacarosa tephra-fall deposit, Misti volcano, southern Peru
These data are derived from the Pleistocene Sacarosa tephra-fall deposit (TFD) which erupted from Misti volcano, Arequipa, southern Peru. The deposit represents a major eruption of Misti and these data are used to characterize the deposit. The radiocarbon ages are from units bracketing the Sacarosa TFD and constrain its eruption age. Whole-rock major and trace element concentrations for...
Summary data on the forage base and critical forage taxa for Chesapeake waterbirds Summary data on the forage base and critical forage taxa for Chesapeake waterbirds
We collated existing quantitative data on avian dietary composition of 58 waterbird species that make use of the Chesapeake Bay. From this database, we quantified the relative importance of forage taxa to the diets of each waterbird species. This data will enable us to develop a comprehensive suite of forage taxa indicators whose abundance and distributions can be monitored as a proxy...
Molecular resources for investigating relationships among freshwater mussels (Bivalvia: Unionoida) with a focus on the genus Alasmidonta Molecular resources for investigating relationships among freshwater mussels (Bivalvia: Unionoida) with a focus on the genus Alasmidonta
Longstanding taxonomic uncertainties have limited conservation efforts for species currently assigned to the freshwater mussel genus Alasmidonta. Here, we present mitochondrial and nuclear DNA sequence data needed to assess the genus- and species-level taxonomy of Alasmidonta. These molecular data allowed us to test whether cryptic diversity exists within Alasmidonta and whether A...
Quetrupillán Volcanic Complex, southern Chile: Argon age data and Pb, Sr, and Nd isotopic data Quetrupillán Volcanic Complex, southern Chile: Argon age data and Pb, Sr, and Nd isotopic data
This dataset accompanies planned publication 'Lava-ice interactions at late Pleistocene trachyte-basaltic andesite fissure eruptions, Quetrupillán Volcanic Complex (39°30′ S, 71°43′ W), southern Chile', as well as planned future publications on this volcanic complex. The Ar/Ar data and the Pb, Sr, and Nd data are for basalt and trachyte lava flows at Quetrupillán volcano. The Ar...
A subset of 2017 Louisiana Coastal Master Plan model output to estimate climate change mitigation potential of Louisiana's coastal area A subset of 2017 Louisiana Coastal Master Plan model output to estimate climate change mitigation potential of Louisiana's coastal area
A subset of the Louisiana's 2017 Coastal Master Plan model output was used to estimate the potential climate mitigation role of Louisiana’s coastal area. Model output of surface water salinity, land/water classification, and area of eight habitats for elapsed years of 6, 11, 16, 26, and 36 were post-processed to estimate habitat areas at years of 2020, 2025, 2030, 2040, and 2050, that...
SYNthetic DEPTH Phase Modeling (SYNDEPTH) SYNthetic DEPTH Phase Modeling (SYNDEPTH)
This python code models event depths by comparing high-frequency (~0.5-0.04 Hz) teleseismic body-wave waveforms to synthetics. High-frequency body waves contain depth information, primarily in the form of depth phases. While lower frequencies are used to generate moment tensor solutions, high-frequency body waves allow for more accurate estimates of source depth. A moment tensor solution...
