In the summer of 2011, the Exploration Vessel NAUTILUS is undertaking a four-month expedition to the Black, Aegean and Mediterranean Seas, and North Atlantic Ocean. The primary goal of the NAUTILUS is to create a focus of international leadership for the development and integration of leading-edge technologies, educational programs, field operations, and public outreach programs for ocean exploration, in partnership with NOAA, National Geographic Society, Office of Naval Research, and other sponsors. To do so, the program uses a complement of deep submergence vehicle systems and “telepresence” technologies to engage scientists, educators and the public, both at sea and ashore, …

Detailed bathymetric maps of the sea floor with centimeter level resolution can be produced by underwater vehicles using multibeam sonars and structured light laser imaging. Over spatial scales up to tens of thousands of square meters it is possible to produce maps gridded to sub centimeter levels. This level of accuracy demands detailed treatments of the sensor relative data, the vehicle navigation data and the vehicle to sensor position and rotational offsets. The presented results will show comparisons between these two sensor modalities. Data have a been collected during recent field programs to the Kolumbo volcanic crater and the Southern …
Legal Education For Sustainability: A Report On Us Progress, John Dernbach
Legal Education For Sustainability: A Report On Us Progress, John Dernbach
John C. Dernbach
This article is an overview of sustainability efforts in US law schools. It describes two sets of drivers for these efforts—inside and outside the legal profession. Drivers from within the legal profession include the American Bar Association as well as several state and local bar associations; law firms and other law organisations; and current and prospective law students. Drivers from outside the legal profession include clients, universities and colleges, nongovernmental organisations, and government. This article then describes what US law schools are now doing in the areas of curriculum, research, buildings and operations, community outreach and service, student life, and …
Implementation And Modification Of A Three-Dimensional Radiation Stress Formulation For Surf Zone And Rip-Current Applications, Nirnimesh Kumar, George Voulgaris, John Warner
Implementation And Modification Of A Three-Dimensional Radiation Stress Formulation For Surf Zone And Rip-Current Applications, Nirnimesh Kumar, George Voulgaris, John Warner

Regional Ocean Modeling System (ROMS v 3.0), a three-dimensional numerical ocean model, was previously enhanced for shallow water applications by including wave-induced radiation stress forcing provided through coupling to wave propagation models (SWAN, REF/DIF). This enhancement made it suitable for surf zone applications as demonstrated using examples of obliquely incident waves on a planar beach and rip current formation in longshore bar trough morphology (Haas and Warner, 2009). In this contribution, we present an update to the coupled model which implements a wave roller model and also a modified method of the radiation stress term based on Mellor (2008, 2011a,b,in …
