SBC LTER: Meteorological and sea surface data from the R/V Pt. Sur Underway Data Acquisition System (UDAS) in the Santa Barbara Channel: LTER11, 2004-09-08 to 2004-09-16

The data described here were collected on LTER11 which took place from 2004-09-08 to 2004-09-16 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.

本次描述的数据集采集自2004年9月8日至2004年9月16日期间开展的LTER11航次，作业平台为瑟角号研究船（RV Pt. Sur）。
自2001年3月起，项目团队于美国加利福尼亚州圣巴巴拉海峡海域每年开展3至4次此类航次，单次航次持续时长约7天。

本次采集的测量数据分为两类基本类型：
1. 走航测量数据：采用流通式系统在3米水深处采集荧光光度、盐度与温度数据，该系统可同步获取连续大气气候观测数据。
2. 走航声学多普勒海流剖面数据：采用RDInstruments Workhorse 300kHz与RDInstruments Ocean Surveyor 75kHz声学多普勒流速剖面仪（ADCP）采集。
