RAPID: Coral reef stress responses to an urban fire https://osprey.bco-dmo.org/project/939628 RAPID: Coral reef stress responses to an urban fire <p><em><strong>NSF Award Abstract:</strong></em><br /> Maui’s coral reefs support subsistence, recreational, and commercial fishing, particularly for the large Native Hawaiian population. In August 2023, hurricane winds and low humidity combined with the recent drought to cause an unprecedented fire in Lahaina, an urban coastal town on the island of Maui. The fire quickly burned over 2170 acres and 2200 structures, releasing ash, particulate matter and potentially toxic materials into the adjacent coastal waters. This project provides novel information on the ecological impacts of wildfires to coral reefs to aid in climate change adaptation and emergency response planning. Cultural perspectives and traditional knowledge of Native Hawaiian community members are incorporated throughout the research process. The project directly supports four students, including a Native Hawaiian student, to participate in activities including field work, data collection, analyses and interpretation, and communication of research results.</p> <p>A wildfire in an urban city located adjacent to a coral reef is unprecedented but may become more common as expanding shoreline development intersects with potentially increased fire risk with climate change. The overall objective of this study is to examine the direct effects of urban wildfires and associated potential stressors - such as reduced water quality, acidification, hypoxia, and heavy metals - on coral reef ecosystem function and the potential for regime shifts favoring benthic algae instead of corals. Using the 2023 Lahaina wildfire as a case study, the project employs a “before-after control-impact” design to compare three west Maui reefs both affected and unaffected by wildfire, with special attention to the anticipated remobilization of organic matter, toxic compounds (e.g., polycyclic aromatic hydrocarbons) and metals following rain events in autumn. Physical and chemical water parameters will constrain the reef-scale carbon cycle and coral metabolism before, during and after runoff events to document the ecological responses to urban fire impacts. This project will support three Early Career Researchers, contribute toward research training for multiple graduate and undergraduate students, and provide valuable information about contaminants and water quality to a community that relies heavily on coral reef resources.</p> Reef stress urban fire largerWorkCitation project eng; USA oceans -156.69354 -156.60764 20.80881 20.93726 2023-10-06 2024-03-02 Lahaina, Maui, Hawaiʻi 0 BCO-DMO catalogue of parameters from Tilt Current Meter data from a post-urban fire water quality study in Lahaina, West Maui, Hawaii from Oct 2023 to Mar 2024 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/1002099.rdf Name: ISO_DateTime_UTC Units: unitless Description: <p>ISO 8601 datetime with timezone (UTC time zone indicated by Z).</p> http://lod.bco-dmo.org/id/dataset-parameter/1002101.rdf Name: Speed Units: centimeters per second (cm/s) Description: <p>water speed</p> http://lod.bco-dmo.org/id/dataset-parameter/1002102.rdf Name: Heading Units: degrees Description: <p>direction (heading)</p> http://lod.bco-dmo.org/id/dataset-parameter/1002103.rdf Name: Velocity_N Units: centimeters per second (cm/s) Description: <p>current velocity North</p> http://lod.bco-dmo.org/id/dataset-parameter/1002104.rdf Name: Velocity_E Units: centimeters per second (cm/s) Description: <p>current velocity East</p> http://lod.bco-dmo.org/id/dataset-parameter/1002105.rdf Name: filename Units: unitless Description: <p>file path</p> http://lod.bco-dmo.org/id/dataset-parameter/1002106.rdf Name: sensor_serial Units: unitless Description: <p>serial number</p> http://lod.bco-dmo.org/id/dataset-parameter/1002107.rdf Name: Site_Name Units: unitless Description: <p>site name (see supplemental site list file for more information)</p> http://lod.bco-dmo.org/id/dataset-parameter/1002108.rdf Name: Site_ID Units: unitless Description: <p>Site identifier (see supplemental site list file for more information)</p> http://lod.bco-dmo.org/id/dataset-parameter/1002109.rdf Name: Site_Lat Units: decimal degrees Description: <p>General site latitude</p> http://lod.bco-dmo.org/id/dataset-parameter/1002111.rdf Name: Site_Lon Units: decimal degrees Description: <p>General site longitude</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 https://osprey.bco-dmo.org/dataset/1001896/data/download download onLine dataset &lt;p&gt;Sensors were deployed within the benthic reef system at the listed sites.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;&lt;u&gt;Lowell Instrument Tilt Current Meters TCM-4:&lt;/u&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Each meter was configured and calibrated using Lowell Instrument’s TCM-4 software prior to deployment.

It contains a tilt compensated compass for bearing measurements. Instrument Name: Tilt Current Meter Instrument Short Name: Instrument Description: Tilt current meters are based upon the property that a tethered object will experience drag inside a current flow. If a restoring force perpendicular to the drag is introduced, the tethered object will tilt until the system of forces is balanced. Therefore, measuring the tilt allows calculation of drag force, from which current speed can be obtained. Measuring the direction of tilt gives current heading. Tilt current meters operate under the drag-tilt principle and are designed to either float or sink depending on the type. A floating tilt current meter typically consists of a sub-surface buoyant housing that is anchored to the sea floor with a flexible line or tether. A sinking tilt current meter is similar, but the housing is designed such that the meter hangs from the attachment point. In either case, the housing tilts as a function of its shape, buoyancy (negative or positive) and the water velocity. Once the characteristics of a housing is known, the velocity can be determined by measuring the angle of the housing and direction of tilt.
