The South Central Climate Adaptation Science Center (CASC) strives to provide actionable science, tools, and information to decision makers in order to address climate change and variability. In this effort, the South Central CASC supports actionable science through multi-institutional and stakeholder driven approaches to assessing the impacts of climate on natural and cultural resources. The South Central CASC is hosted by the University of Oklahoma with six consortium partners: Texas Tech University, The Chickasaw Nation, The Choctaw Nation of Oklahoma, Louisiana State University, Oklahoma State University, and University of New Mexico. During the period of 2019 – 2024, the South Central CASC consortium will strive...
Coral Ba/Ca is a proxy for seawater barium concentration that varies with upwelling, terrigenous input, and marine productivity whereas coral Sr/Ca varies with temperature. We examine monthly coral Ba/Ca and Sr/Ca before and during offshore oil exploration in a Siderastrea siderea coral from West Flower Garden Bank located on the continental shelf edge in the Gulf of Mexico. Coral Ba/Ca variations lack pulses driven by upwelling or river outflow and are not in sync with coral Sr/Ca that exhibit a different seasonal pattern. Seasonal variations in chlorophyll-a concentration negatively correlate with coral Ba/Ca explaining 25% of that variability. A significant increase in mean coral Ba/Ca of 1.76 μmol/mol between...

Recent research has linked the climate variability associated with ocean-atmosphere teleconnections to impacts rippling throughout environmental, economic, and social systems. This research reviews recent literature through 2021 in which we identify linkages among the major modes of climate variability, in the form of ocean-atmosphere teleconnections, and the impacts to temperature and precipitation of the South-Central United States (SCUSA), consisting of Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. The SCUSA is an important areal focus for this analysis because it straddles the ecotone between humid and arid climates in the United States and has a growing population, diverse ecosystems, robust agricultural...

Abstract (from ESSD): The response of the hydrological cycle to anthropogenic climate change, especially across the tropical oceans, remains poorly understood due to the scarcity of long instrumental temperature and hydrological records. Massive shallow-water corals are ideally suited to reconstructing past oceanic variability as they are widely distributed across the tropics, rapidly deposit calcium carbonate skeletons that continuously record ambient environmental conditions, and can be sampled at monthly to annual resolution. Climate reconstructions based on corals primarily use the stable oxygen isotope composition (δ18O), which acts as a proxy for sea surface temperature (SST), and the oxygen isotope composition...

Tribal nations are one of the most vulnerable populations to climate change in the United States, because of their reliance upon the natural environment to sustain traditional ways of life and current lack of training and resources to respond to climate change impacts. This project sought to increase south-central U.S. tribes’ basic knowledge of climate science, connect them with tools to assess their communities’ vulnerabilities, and build their skills to develop adaptation and mitigation strategies. Researchers conducted multiple two-day climate training sessions for Native American tribes in Louisiana and New Mexico. The trainings emphasized regionally specific scientific and social scientific aspects of climate...

Led by members of the South Central Climate Science Center (SC CSC) consortium, this project builds upon the successes of the 2014 and 2016 trainings to develop and implement professional development training for graduate students, postdocs, and early-career researchers within the SC CSC region. The objectives were: (1) introduce a new cohort of early-career researchers to the research challenges of the SC CSC, offering them insight into how their research fits into the broader priorities of the SC CSC and applicability to end user needs; (2) facilitate interdisciplinary interactions to discuss research with peers and foster collaborative opportunities; and (3) generate a syllabus, knowledge tests, and specific...

Many inland bodies of water in western Louisiana are receiving too much sediment and nutrient pollution from upstream which has caused declines in the health of many fisheries. These bodies of water include many traditional lake-based fisheries of the Chitimacha Tribe of Louisiana (CTL), and fisheries used by visitors, providing critical tourism and economic development dollars to the region. The goal of the Coastal Indigenous Fisheries Assessment (CIFA) is to study the long-term health and ecology of fisheries and water bodies in west-central Louisiana. This project will be a collaboration between leaders and scientists from the Chitimacha Tribe of Louisiana, Louisiana State University and Florida State University...

Investigating the complex natural and cultural resource management challenges we face today requires building diverse, interdisciplinary research teams. Robust stakeholder engagement is also critical for ensuring that publicly funded science answers questions that are relevant to natural and cultural resource management decisions. Early career scientists who learn how to engage with multi-disciplinary research teams and stakeholders in the early stages of their career have a competitive advantage in the workforce and can help develop actionable science that addresses critical management questions. This project built upon the successes of the 2014 Early Career Training to develop and host a week-long professional...
Tribal nations are at the forefront of adaptation to climate change in the United States, because of their reliance upon the natural environment to sustain traditional ways of life yet the current lack of training and resources to respond to climate change impacts remains a challenge. Working with the South Central Climate Science Center (SC CSC), our team of climate scientists and anthropologists worked with tribal professionals in Louisiana and New Mexico to increase their basic knowledge of climate science, connect them with tools to assess their communities’ vulnerabilities, and helped them build their skills to develop adaptation and mitigation strategies. Our team held biweekly conference calls in consultation...
Abstract (from SAGEJournals): The proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) candidate site of West Flower Garden Bank (27.8762°N, 93.8147°W) is an open ocean location in the Gulf of Mexico with a submerged coral reef and few direct human impacts. Corals contain highly accurate and precise (<±1 year) internal chronologies, similar to tree rings, and their exoskeletons are formed of aragonite and can be preserved in the rock record. Here we present results from a large Siderastrea siderea coral (core 05WFGB3; 1755–2005 CE) sampled with annual and monthly resolutions that show clear markers of global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C, 239+240Pu)...
