研究项目重点
满足莫比
One of the 菠菜网lol正规平台 研究基金会’s most fascinating projects is “MOBY,” short for Marine Optical BuoY, an autonomous optical buoy which is moored off the island of 夏威夷的拉奈岛. The buoy is a primary ocean observatory for the calibration of satellite 海洋颜色传感器. By measuring water-leaving radiance, and assessing the resulting water color, MOBY provides data that satellites can use to continuously calibrate and validate their on-orbit measurements.
The MOBY design process started with NOAA funding in 1988, and in 1992 菠菜网lol正规平台’s Moss Landing Marine Laboratories (MLML) was selected through a NASA grant process to participate in the engineering and construction of the initial system. 随后进行了施工 by deployments of prototypes, first in Monterey Bay (1993) and then in Hawaii (1995). The buoy was tested in the fall of 1996 in Hawaii, and MOBY became operational at the current Lanai site in July 1997.
A Hawaii-based MLML team of researchers, scientists, programmers, technicians, and divers has primary responsibility for maintaining and calibrating the buoy. 由 马克Yarbrough, the team monitors and evaluates the data that MOBY produces.
“MOBY has become a life’s work for me,” Yarbrough says. “定期的机会 work at sea and face new technological and scientific challenges almost daily has provided motivation and held my interest for decades. 有很大的满足感 in knowing your work can provide tangible benefit to the extremely valuable satellite 我们支持的项目.”
During prevailing trade wind conditions, the buoy’s location off the coat of Lanai is sheltered in the lee of the island, yet it is far enough offshore to minimize atmospheric perturbations associated with the island’s wake. There are two complete MOBY systems, 一个 of which is moored and operational at any given time. 典型的持续时间 a single MOBY deployment is between three and four months. 在此期间， other MOBY is maintained and refurbished, and its MOS recalibrated to prepare it for deployment in relief of its alternate.
Today, MOBY is in its 21st year of continuous operation, supporting over a dozen U.S. and international ocean color satellite programs.
