Caption from Oceanus online article:
The research team uses a high-pressure hose to fluidize sand on the seafloor so that they could push pipes up to 8 feet into the seafloor. Once the sand solidifies, they attach their sensors to tops of the pipes. From left are Seth Zippel, Levi Gorrell, Regina Yopak, Britt Raubenheimer, Steve Elgar, and Dana Kurtz.
Image Of the Day caption:
MIT-WHOI Joint Program student Melissa Moulton and colleagues in the PV Lab at WHOI undertook an study recently to investigate where and how rip currents form on beaches. They used a landing craft to dredge a 150-foot long, 90-foot-wide channel in shallow water at a research beach in Duck, N.C., to induce the formation of rips. The research team then used a high-pressure hose (pictured) to fluidize sand on the seafloor, so that they could push pipes up to 8 feet into the seafloor. Once the sand re-settled, they attached sensors to the pipes to gather data tracking how rips form.
