Environmental Fluid Dynamics Laboratory

ORE's Environmental Fluid Dynamics Laboratory (EFDL) focuses on the study of coastal marine processes including turbulent dispersal of pollutants and nutrients, wave dynamics, and sediment transport. Instrumentation for lab and field measurements includes acoustic Doppler current meters (ADCMs) and acoustic Doppler current profilers (ADCPs) for ocean current and wave measurements, an acoustic doppler velocimeter (ADV), pressure sensors, and thermistors. Several wave tanks are accessible for small‐scale experiments and demonstrations. These are used to demonstrate fluid flow phenomena including wave breaking, down‐slope currents, internal waves in stratified fluids, and rotational effects such as spin‐up, Ekman flow and geostrophy.

Kilo Nalo Oahu Reef Observatory

The Kilo NaloOahu Reef Observatory is located on the south shore of Oahu, east of downtown Honolulu and west of Waikiki and Ala Moana. Kilo Nalu provides a window into the physical, biological and chemical environment of nearshore coral reefs, as well as data and power connections to a suite of observational instruments that resolve waves, tides, currents and nearshore water quality. The observatory is managed and maintained by ORE.

Field Work and In-Ocean Experiment

Current Meter Retrieving Connecing floats

The department maintains research facilities at Kewalo Basin and Snug Harbor for field workand in‐ocean experiments. These facilities include field research equipment and instrumentation, access to a 17‐ft motorboat and an 18‐m coastal research vessel, as well as machine shop support. A 7‐acre in‐ocean test range off Kewalo Basin extends from 5 to 20 meters depth with test platforms equipped with land‐based power supply outlets and data connections. Field equipment includes SCUBA diving gear, acoustic current profilers, current meters, wave gauges, anemometers, buoys and mooring equipment. The field research facilities support study of ocean and coastal structures and materials, wave dynamics and sediment transport.

Kaimikai-O-Kanaloa Pisces V & IV

ORE maintains research facilities at Kewalo Basin and at the UH Marine Center (at Pier 35 in Honolulu Harbor) for field work and in‐ocean experiments. These facilities include field research equipment and instrumentation (with machine shop support), as well as access to various ocean vessels. In addition to the large ships, Kilo Moana and Ka'imikai‐O‐Kanaloa, this includes the Kilo Kai, a 25‐ft Force Marine twin‐outboard motorboat for local work, and the Ho'okele, a 38‐ft twin diesel inboard motorboat suited for long–range work. Local boats can be hired as necessary. Field equipment includes SCUBA diving gear, acoustic current profilers, current meters, wave gauges, anemometers, buoys, and mooring equipment. The field research facilities support study of ocean and coastal structures and materials, wave dynamics and sediment transport. A 7 acre, 5 to 20 foot deep, in‐ocean test range is located off Kewalo Basin and is equipped with test platforms carrying land‐based power supply outlets and data connections.

The Hawaii Undersea Research Laboratory (HURL) is one of six national laboratories which comprise the National Oceanic and Atmospheric Administration's National Undersea Research Program. HURL operates two deep diving (2000m) submersibles, the PISCES IV and PISCES V, and a remotely operated vehicle (ROV). The ROV and submersibles operate off the 225‐foot research vessel, Kaimikai‐O‐Kanaloa, obtained for the university and largely supported by HURL. The submersibles, ROV, and their mothership conduct a wide range of engineering and scientific research activities. Time on the submersibles and ROV is available to the faculty and students who submit a suitable proposal. HURL and ORE have a close working relationship on all levels. Many students in ORE find thesis projects and financial support studying various aspects of submersible dynamics and ROV operations, as well as helping to develop new instrumentation, controls and applications.

The ALOHA Cabled Observatory provides another avenue for ocean observations. Since June 2011, the ALOHA Cabled Observatory (ACO) has provided power, network communications and timing to instruments at a seafloor node 4728 m below the water surface, 100 km north of Oahu. ACO is a prototypical example of a deep observatory system that uses a retired first‐generation fiber‐optic telecommunications cable. The cabled observatory system provides infrastructure for continuous, interactive ocean sampling enabling new measurements and new modes of ocean observing which integrate ship and cabled observations. Present sensors measure currents, pressure, temperature, and salinity, along with video and acoustics. Students are able to analyze data from the ACO for projects, design and fabricate new sensors for the system, and participate on service cruises with a state‐of‐the‐art ROV.

Computing Facility

Computer clusters operated by individual faculty members are available to their students for research. The UH ITS High Performance Cluster is another valuable computing resources available to members of the UH community. ORE also maintains a number of software packages available to all students. These include:

  • ArcGIS
  • AutoDesk Mech, Map Series, Civil Series, V1Z4, and Express Viewer
  • AutoCAD
  • Automated Coastal Engineering System (ACES)
  • Coastal Engineering Manual (CEM)
  • DELFTSHIP (Hydrostatics package)
  • Matlab
  • MathCAD
  • Mathematica
  • Microstation SE
  • Photoshop
  • Tecplot (graphics)

Students taking ORE 630 are also given access to the finite element package ANSYS, which is maintained by the Department of Mechanical Engineering.
