(Version 1) Version Date 2020-10-28 [if applicable, indicate subset used]. doi:10.26008/1912/bco-dmo.827812.1 [access date] seawater temperature,1996-2018 Dataset Description: Methods and Sampling: &lt;p&gt;From publication Limnology and Oceanography&lt;/p&gt; &lt;p&gt;Environmental conditions&lt;/p&gt; &lt;p&gt;Seawater temperature and rainfall were tested for their capacity to account for variation in the dynamics of small corals in the target size range. Seawater temperature was measured every 15–30 minutes using loggers deployed in two locations. Most measurements came from Yawzi Point, where temperature was recorded at 11-m depth using a Ryan Industries thermistor (± 0.3°C) from 1996 to June 1997, and from November 1997 to August 1999. From May 1997 to October 1997, and from August 1999 to August 2001, Optic Stowaway loggers (± 0.2°C) were used, and from August 2001 to the present, Hobo Aquapro loggers (± 0.2°C) were used. Gaps in the time-series of seawater temperature from Yawzi Point were created by periodic equipment malfunction, and these gaps were filled with records from 14-m depth at Tektite (~ 500 m southwest) that were recorded with Hobo Aquapro loggers. A representative year (2015–2016) of temperature records from Yawzi Point and Tektite showed that the daily temperature differed by ≤ 0.1°C between these sites (mean = 0.043 ± 0.003°C, n = 368). Temperature was not consistently measured at the six sites at which small corals were surveyed, but records from 2016–2017 show that the mean (± SE) variation between Cabritte Horn (9 m depth, easternmost site) and White Point (5 m depth, westernmost site) was 0.14 ± 0.01°C (warmer to the west). Among site differences were less than the resolution of the loggers (± 0.2°C). Temperature records from Yawzi Point were averaged by day and used to create two summary statistics for the 12 months between 1 August and 31 July of the subsequent year for 22 years: mean temperature and an annualized summation of thermally extreme days.&lt;/p&gt; &lt;p&gt;The mean temperature was used to characterize the year between samplings. The extent to which temperature potentially was unfavorable to corals was evaluated by calculating the number of upwardly thermally extreme days over 12 months (in units of weeks). In this calculation, hot days were gauged relative to the local coral bleaching threshold for sea surface temperature (29.4°C), as determined by the United States National Oceanic and Atmospheric Administration (http://coralreefwatch.noaa.gov/vs/index.php). Days between 1 August and 31 July of the following year were ranked by the extent to which their daily mean temperature exceeded 29.4°C, with a rank of 0 for ≤ 29.4°, a rank of 1 for &amp;gt; 29.4°C but ≤ 30.4°C, and a rank of 2 for &amp;gt; 30.4 but ≤ 31.4°C (mean daily temperature did not exceed 31.4°C). Annualized summaries of thermal extremes were obtained by summing the daily ranks in each 12 month period and dividing by 7 to provide units of weeks.&lt;/p&gt; Funding provided by NSF Division of Environmental Biology (NSF DEB) Award Number: DEB-1350146 Award URL: https://www.nsf.gov/awardsearch/show-award?AWD_ID=1350146 completed Peter J.

RUI-LTREB Renewal: Three decades of coral reef community dynamics in St. John, USVI: 2014-2019 http://coralreefs.csun.edu/ RUI-LTREB Renewal: Three decades of coral reef community dynamics in St. John, USVI: 2014-2019 <p>Describing how ecosystems like coral reefs are changing is at the forefront of efforts to evaluate the biological consequences of global climate change and ocean acidification. Coral reefs have become the poster child of these efforts. Amid concern that they could become ecologically extinct within a century, describing what has been lost, what is left, and what is at risk, is of paramount importance. This project exploits an unrivalled legacy of information beginning in 1987 to evaluate the form in which reefs will persist, and the extent to which they will be able to resist further onslaughts of environmental challenges. This long-term project continues a 27-year study of Caribbean coral reefs. The diverse data collected will allow the investigators to determine the roles of local and global disturbances in reef degradation. The data will also reveal the structure and function of reefs in a future with more human disturbances, when corals may no longer dominate tropical reefs.</p> <p>The broad societal impacts of this project include advancing understanding of an ecosystem that has long been held emblematic of the beauty, diversity, and delicacy of the biological world. Proposed research will expose new generations of undergraduate and graduate students to natural history and the quantitative assessment of the ways in which our planet is changing. This training will lead to a more profound understanding of contemporary ecology at the same time that it promotes excellence in STEM careers and supports technology infrastructure in the United States. Partnerships will be established between universities and high schools to bring university faculty and students in contact with k-12 educators and their students, allow teachers to carry out research in inspiring coral reef locations, and motivate children to pursue STEM careers. Open access to decades of legacy data will stimulate further research and teaching.</p> RUI-LTREB largerWorkCitation project eng; USA oceans -64.73152 -64.7208 18.30702 18.31714 1996-01-01 2018-12-31 USVI 0 BCO-DMO catalogue of parameters from Seawater temperature between Cabritte Horn and White Point on the south shore of St. John, US Virgin Islands, 1996-2018 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/827828.rdf Name: Date Units: unitless Description: <p>date of measurement formatted as yyyy-mm-dd</p> http://lod.bco-dmo.org/id/dataset-parameter/827829.rdf Name: Temp Units: degrees Celsius Description: <p>daily seawater temperature</p> GB/NERC/BODC > British Oceanographic Data Centre, Natural Environment Research Council, United Kingdom Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact 129648 https://darchive.mblwhoilibrary.org/bitstream/1912/26357/1/dataset-827812_seawater-temperature-submission-lo__v1.tsv download https://doi.org/10.26008/1912/bco-dmo.827812.1 download onLine dataset &lt;p&gt;From publication Limnology and Oceanography&lt;/p&gt; &lt;p&gt;Environmental conditions&lt;/p&gt; &lt;p&gt;Seawater temperature and rainfall were tested for their capacity to account for variation in the dynamics of small corals in the target size range.

Instrument Name: Thermistor Instrument Short Name: Instrument Description: A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals. The temperature response is also different; RTDs are useful over larger temperature ranges, while thermistors typically achieve a higher precision within a limited temperature range, typically 90C to 130C.
