The Absolute and Relative Composition of Holocene Reef Cores From the Florida Keys Reef Tract The Absolute and Relative Composition of Holocene Reef Cores From the Florida Keys Reef Tract
This data release provides a summary of the absolute percent composition of all recovered material and relative percent composition of coral taxa in the Holocene-aged intervals of 61 coral-reef cores collected throughout the Florida Keys reef tract (FKRT) housed in the USGS Core Archive in St. Petersburg, FL. Estimated ages for distinct depths within each core are also provided; those...
Experimental Data on Construction and Erosion of Orbicella Coral Reefs in the Florida Keys, U.S.A. Experimental Data on Construction and Erosion of Orbicella Coral Reefs in the Florida Keys, U.S.A.
The USGS Coral Reef Ecosystems Studies project provides science that helps resource managers tasked with the stewardship of coral reef resources. This data release contains data on coral-growth rates for Orbicella sp. coral colonies grown at five sites on the Florida Keys reef tract from 2013 to 2015, survey data for census-based carbonate budgeting at Hen and Chickens Reef (Islamorada...
Descriptive Core Logs, Core Photographs, Radiocarbon Ages, and Accretion Data from Holocene Reef Cores Collected Throughout the Florida Keys Reef Tract Descriptive Core Logs, Core Photographs, Radiocarbon Ages, and Accretion Data from Holocene Reef Cores Collected Throughout the Florida Keys Reef Tract
The USGS core archive (Reich and others, 2009; USGS Core Archive) houses an extensive collection of coral-reef cores that USGS researchers have collected from throughout the Florida Keys reef tract (FKRT; fig. 1). USGS scientists have compiled all available data on the 71 core records that recovered Holocene reef framework, including radiometric ages (radiocarbon and U-series), data on...
Experimental data comparing two coral grow-out methods in nursery-raised Acropora cervicornis Experimental data comparing two coral grow-out methods in nursery-raised Acropora cervicornis
Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef-restoration efforts to date. As part of the USGS Coral Reef Ecosystems Studies project (http://coastal.er.usgs.gov/crest/), we investigated skeletal characteristics of nursery-grown staghorn coral reared using two commonly used grow-out methods at Mote Tropical Research Laboratory...

A 3,000‐year lag between the geological and ecological shutdown of Florida's coral reefs A 3,000‐year lag between the geological and ecological shutdown of Florida's coral reefs
The global‐scale degradation of coral reefs has reached a critical threshold wherein further declines threaten both ecological functionality and the persistence of reef structure. Geological records can provide valuable insights into the long‐term controls on reef development that may be key to solving the modern coral‐reef crisis. Our analyses of new and existing coral‐reef cores from...

Plasticity in skeletal characteristics of nursery-raised staghorn coral, Acropora cervicornis Plasticity in skeletal characteristics of nursery-raised staghorn coral, Acropora cervicornis
Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef restoration efforts to date. We compared linear extension, calcification rate, and skeletal density of nursery-raised A. cervicornis branches reared for 6 months either on blocks attached to substratum or hanging from PVC trees in the water column. We demonstrate that branches...

The structure and composition of Holocene coral reefs in the Middle Florida Keys The structure and composition of Holocene coral reefs in the Middle Florida Keys
The Florida Keys reef tract (FKRT) is the largest coral-reef ecosystem in the continental United States. The modern FKRT extends for 362 kilometers along the coast of South Florida from Dry Tortugas National Park in the southwest, through the Florida Keys National Marine Sanctuary (FKNMS), to Fowey Rocks reef in Biscayne National Park in the northeast. Most reefs along the FKRT are...

The relationship between the ratio of strontium to calcium and sea-surface temperature in a modern Porites astreoides coral: Implications for using P. astreoides as a paleoclimate archive The relationship between the ratio of strontium to calcium and sea-surface temperature in a modern Porites astreoides coral: Implications for using P. astreoides as a paleoclimate archive
An inverse relationship has been demonstrated between water temperature and the ratio of strontium to calcium (Sr/Ca) in coral aragonite for a number of Pacific species of the genus Porites. This empirically determined relationship has been used to reconstruct past sea-surface temperature (SST) from modern and Holocene age coral archives. A study was conducted to investigate this...
