SBC LTER: Meteorological and sea surface data from the R/V Pt. Sur Underway Data Acquisition System (UDAS) in the Santa Barbara Channel: LTER15, 2006-02-02 to 2006-02-09

The data described here were collected on LTER15 which took place from 2006-02-02 to 2006-02-09 on the RV Pt. Sur. Cruises have been conducted in the Santa Barbara Channel, California, USA, 3-4 times per year since March, 2001 and are approximately 7 days in length. There are 2 basic types of measurements: Underway measurements: fluorometry, salinity and temperature are collected at a depth of 3m with a flow-through system which also includes continuous atmospheric climate measurements. Underway acoustic doppler current profiles were collected using a RDInstruments Workhorse 300kHz and RDInstruments Ocean Surveyor 75kHz ADCP.

本数据集采集自2006年2月2日至2006年2月9日开展的LTER15科考航次，作业船为RV Pt. Sur号科研船。自2001年3月起，该类航次每年在美国加利福尼亚州圣巴巴拉海峡执行3至4次，单次航次时长约7天。本次采集的测量数据包含两类基本类型：
1. 走航测量（Underway measurements）：采用流通式观测系统在3米水深处采集荧光测定、盐度与温度数据，该系统同步获取连续的大气气候观测数据。
2. 走航声学多普勒海流剖面测量数据：使用RDInstruments公司生产的Workhorse 300kHz与Ocean Surveyor 75kHz声学多普勒海流剖面仪（ADCP）采集得到。
