Sampling Methods

During Project SANTA CLAµS, data were collected by a variety of methods, some described subsequently in more detail (see Group Reports). Continuous underway measurements of selected surface ocean properties and local meteorology were obtained and logged. Continuous water column profiles of conductivity, temperature, beam transmission, PAR, fluorescence and light scatter were obtained using the CTD system. Discrete water samples were obtained using rosette-mounted Go-Flo bottles. Sinking particulate matter was collected at several sites using sequencing, bottom-moored sediment traps.
