Time series data of water surface elevation, wave height, and water column currents and temperature were acquired at seven locations for 86 days off of Waiakane on the south coast of the island of Molokai, Hawaii, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reef were as follows: MKK18C01 – offshore MKK18C02 and MKK18C09 – fore reef MKK18C18 – reef crest MKK18C20 – outer reef flat MKK18C22 – middle reef flat MKK18C22 – inner reef flat
Tidal cycle water velocities were measured at transects in the Bushy Park Reservoir using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). Five transects were measured on August 5, 2014 and November 5, 2014, and two transects were measured on March 26, 2015 and April 23, 2015. The data were collected every 30 minutes over a tidal cycle . The data were georeferenced with differential GPS receivers with submeter accuracy. Data were processed using the "Velocity Mapping Toolbox" (Parsons et al., 2013). Any data assigned a value of "-9999" are bad or missing data and should not be used for analysis. Parsons, D.

Vertical velocities profiles were measured at 15-minute intervals at six locations in the Bushy Park Reservoir using self-contained Sontek Argonaunt XRs upward-facing acoustic Doppler current profilers (ADCPs) with a frequency of either 1,500 or 3,000 kiloHertz (kHz)). The ADCPs were deployed between December 2013 and May 2015. Up to four sites were collected concurrently. Data were processed using ViewArgonaut, a software package developed by SonTek (http://www.sontek.com/softwaredetail.php?ViewArgonaut-Software-21) to compute the average velocity vector (magnitude and direction) for each time step (15-minute) at the location.
The western coastline of Alaska is highly susceptible to coastal storms, which can cause coastal erosion, flooding, and have other pernicious effects to the environment and commercial efforts. The reduction in ice coverage due to climate change could potentially increase the frequency and degree of coastal flooding and erosion. Further, estuaries and delta systems act as conduits for storm surges, so when there is less nearshore ice coverage, these systems could introduce storm surge into terrestrial environments unaccustomed to saline intrusion, flooding, or other alien biogeochemical factors.This presentation provides an update on a project that is quantifying the effect of reduced nearshore ice coverage on coastal...
