AltaSea hosted more than a dozen high school students — hailing from San Pedro, the Palos Verdes Peninsula, Compton and Whittier — on Thursday to celebrate completing a six-week summer mentorship program during which they learned to build underwater robots.

Their handiwork was tested out in pools and in the ocean channel in what was a fitting end-of-summer event.

The event marked the end of the six-week mentorship program. During the program, students learned how to build underwater robots, how marine energies work and how to grow regenerative aquaculture.

The students also received certificates of completion, handed out by state Sen. Steven Bradford, and a representative from U.S. Rep. Nanette Barragan’s office. The program was also awarded $15,000 from energy company Phillips 66 to help fund future programs.
