The eBird enterprise: An integrated approach to development and application of citizen science

Creator:: Sullivan, Brian L., Aycrigg, Jocelyn L., Barry, Jessie H., Bonney, Rick E., Bruns, Nicholas, Cooper, Caren B., Damoulas, Theo, Dhondt, Andre A., Dietterich, Thomas G., Farnsworth, Andrew, Fink, Daniel, Fitzpatrick, John W., Fredericks, Thomas, Gerbracht, Jeff, Gomes, Carla, Hochachka, Wesley M., Iliff, Marshall J., Lagoze, Carl, La Sorte, Frank A., Merrifield, Matthew, Morris, Will, Phillips, Tina B., Reynolds, Mark, Rodewald, Amanda D., Rosenberg, Kenneth V., Trautmann, Nancy M., Wiggins, Andrea, Winkler, David W., Wong, Weng-Keen, Wood, Christopher L., Yu, Jun, and Kelling, Steve
Abstract:: Citizen-science projects engage volunteers to gather or process data to address scientific questions. But citizen-science projects vary in their ability to contribute usefully for science, conservation, or public policy. eBird has evolved from a basic citizen-science project into a collective enterprise, taking a novel approach to citizen science by developing...

The Cascade of Tidal Energy from Low to High Modes on a Continental Slope

Creator:: Kelly, Samuel M., Nash, Jonathan D., Martini, Kim I., Alford, Matthew H., and Kunze, Eric
Abstract:: The linear transfer of tidal energy from large to small scales is quantified for small tidal excursion over a near-critical continental slope. A theoretical framework for low-wavenumber energy transfer is derived from “flat bottom” vertical modes and evaluated with observations from the Oregon continental slope. To better understand the observations,...

Observations of Internal Tides on the Oregon Continental Slope

Creator:: Martini, Kim I., Alford, Matthew H., Kunze, Eric, Kelly, Samuel M., and Nash, Jonathan D.
Abstract:: A complex superposition of locally forced and shoaling remotely generated semidiurnal internal tides occurs on the Oregon continental slope. Presented here are observations from a zonal line of five profiling moorings deployed across the continental slope from 500 to 3000 m, a 24-h expendable current profiler (XCP) survey, and five...

Internal Bores and Breaking Internal Tides on the Oregon Continental Slope

Creator:: Martini, Kim I., Alford, Matthew H., Kunze, Eric, Kelly, Samuel M., and Nash, Jonathan D.
Abstract:: Observations of breaking internal tides on the Oregon continental slope during a 40-day deployment of 5 moorings along 43°12'N are presented. Remotely generated internal tides shoal onto the slope, steepen, break, and form turbulent bores that propagate upslope independently of the internal tide. A high-resolution snapshot of a single bore...

The Direct Breaking of Internal Waves at Steep Topography

Creator:: Klymak, Jody M., Legg, Sonya, Alford, Matthew H., Buijsman, Maarten, Pinkel, Robert, and Nash, Jonathan D.
Abstract:: Internal waves are often observed to break close to the seafloor topography that generates them, or from which they scatter. This breaking is often spectacular, with turbulent structures observed hundreds of meters above the seafloor, and driving turbulence dissipations and mixing up to 10,000 times open-ocean levels. This article provides...

Particle distributions and dynamics in the euphotic zone of the North Pacific Subtropical Gyre

Creator:: Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., Karl, David M., Letelier, Ricardo M., and White, Angelicque E.
Abstract:: During the summer of 2012, we used laser diffractometry to investigate the temporal and vertical variability of the particle size spectrum (1.25–100 µm in equivalent diameter) in the euphotic zone of the North Pacific Subtropical Gyre. Particles measured with this optical method accounted for ∼40% of the particulate carbon stocks...

Three-Dimensional Double-Ridge Internal Tide Resonance in Luzon Strait

Creator:: Buijsman, Maarten C., Klymak, Jody M., Legg, Sonya, Alford, Matthew H., Farmer, David, MacKinnon, Jennifer A., Nash, Jonathan D., Park, Jae-Hun, Pickering, Andy, and Simmons, Harper
Abstract:: The three-dimensional (3D) double-ridge internal tide interference in the Luzon Strait in the South China Sea is examined by comparing 3D and two-dimensional (2D) realistic simulations. Both the 3D simulations and observations indicate the presence of 3D first-mode (semi)diurnal standing waves in the 3.6-km-deep trench in the strait. As in...

Energy Flux and Dissipation in Luzon Strait: Two Tales of Two Ridges

Creator:: Alford, Matthew H., MacKinnon, Jennifer A., Nash, Jonathan D., Simmons, Harper, Pickering, Andy, Klymak, Jody M., Pinkel, Robert, Sun, Oliver, Rainville, Luc, Musgrave, Ruth, Beitzel, Tamara, Fu, Ke-Hsien, and Lu, Chung-Wei
Abstract:: Internal tide generation, propagation, and dissipation are investigated in Luzon Strait, a system of two quasi-parallel ridges situated between Taiwan and the Philippines. Two profiling moorings deployed for about 20 days and a set of nineteen 36-h lowered ADCP-CTD time series stations allowed separate measurement of diurnal and semidiurnal internal...
