SBC LTER: Ocean: Ocean Currents and Biogeochemistry: Nearshore water profiles (monthly CTD and chemistry), ongoing since 2000

This data package contains water chemistry measurements taken
monthly at these reefs in the nearshore areas of the Santa Barbra
Channel, CA, USA: Arroyo Quemado, Bullito, Naples, Arroyo Burro,
Mohawk and Carpinteria. Measurements include standard CTD
parameters, nutrients, pigments, particulate CN, total dissolved N
and P, stable isotopes of C and N (not all parameters are measured
at all stations). Sampling began in November 2000. Some stations
are sampled only occasionally. During the first 2 years, CTD data
were collected with a SBE19 Seacat Profiler and water samples with
a pump. Starting in February 2003, a SBE19-Plus with a rosette
sampler was used. There are 3 tables in this dataset. Water chemistry and profiles
from "registered stations" (see geographic coverage) are
in 2 tables with "registered" in their name. CTD
profiles are often collected ad hoc, or as "stations of
opportunity". These have been collected in a third table as
"non-registered". The station codes for these may be
reused, and are not recorded in metadata (but can be found in
data).

本数据包包含在美国加利福尼亚州圣巴巴拉海峡近岸区域的以下珊瑚礁每月采集的水化学测量数据：Arroyo Quemado、Bullito、Naples、Arroyo Burro、Mohawk及Carpinteria。测量参数包括标准CTD参数、营养盐、色素、颗粒态碳氮（CN）、总溶解氮（N）与磷（P）、碳氮稳定同位素（并非所有站点均测量所有参数）。

采样始于2000年11月。部分站点仅偶尔采样。前两年，使用SBE19 Seacat Profiler采集CTD数据，使用泵采集水样。自2003年2月起，改用配备rosette sampler的SBE19-Plus。

本数据集包含3个表格。来自"注册站点"（详见地理覆盖范围）的水化学数据及剖面数据存储于名称含"registered"的2个表格中。CTD剖面数据常通过临时采样或"机会站点"采集，此类数据存储于第三个名为"non-registered"的表格中。这些站点的编码可能重复使用，且未记录在元数据中（但可在数据内找到）。
