Broad-scale hydrography from CTDs deployed from 30 cruises on the R/V Albatross IV, R/V Endeavor, and R/V Oceanus in the Gulf of Maine and Georges Bank from 1995-1999 (GB project)

<h2>Broad-scale Hydrography, 1995 - 1999</h2> <p><strong>If you encounter any questionable values or have other questions, contact:</strong> David Mountain National Marine Fisheries Servce, NEFC Woods Hole, MA 02540 voice: 508 495 2000 fax: [phone] email: <a href=\"mailto:[e-mail]\">[e-mail]</a></p> <h2>File Descriptions:</h2> <p>At level 1 in the comments field, the user has three options for selecting CTD profile data available from this cruise:</p> <p>mark5CTD link - Links the user to the Neil Brown Mark-5 CTD profiles. The Mark-5 profiler, has a higher sampling rate then the SeaBird SEACAT, was instrumented with an expanded suite of sensors and deployed almost exclusively at GLOBEC Standard stations.</p> <p>seabirdCTD link - Links the user to the SeaBird SEACAT profiler deployed with the bongo plankton net tow system at Standard and Intermediate stations. The upcast portion of the tow is the most reliable and that is what is reported here. These profiles do not contain the parameters: light transmission, fluorescence, and scalar par. Users working with the plankton data may want to work with this data set exclusively.</p> <p>primary link - Links the user to the best hydrography coverage available for the cruise. The \"primary version\", in most cases, is a composite of both the Mark-5 and SEACAT CTD casts. These casts have been extracted from their respective cruise files and sorted by time. As a result, the reported cast and station numbers are frequently duplicated and random in order. When present, SeaBird profiles are identified with a one hundred series cast number to distinguish from a Mark-5 profile, however, this convention is inconsistent and does not always appear in all cruises (primary link only).</p> <p><em>Prepared by: Maureen Taylor, NMFS/Woods Hole, 2/7/1996<br /> last updated: 19 Nov. 2004; gfh </em></p>## 1995-1999年大范围海洋水文测量数据集 若您遇到任何可疑数值或有其他疑问，请联系：大卫·芒廷（David Mountain），美国国家海洋渔业局（National Marine Fisheries Service, NMFS）东北渔业科学中心（Northeast Fisheries Science Center, NEFC），伍兹霍尔，马萨诸塞州02540；电话：508 495 2000，传真：508 495 2258，邮箱：[e-mail] ## 文件说明： 在注释字段的一级选项中，用户可从本次航次的可用CTD（Conductivity, Temperature, Depth，温盐深仪）剖面数据中选择以下三种获取方式： mark5CTD链接：该链接将引导用户访问尼尔·布朗Mark-5型CTD剖面数据。Mark-5型剖面仪的采样率高于SeaBird SEACAT型剖面仪，配备扩展套件传感器，且几乎仅部署于全球海洋生态系统动力学研究（Global Ocean Ecosystem Dynamics, GLOBEC）标准站位。 seabirdCTD链接：该链接将引导用户访问搭载邦戈浮游生物网拖网系统的SeaBird SEACAT型剖面仪数据，该系统应用于标准站位与中间站位。拖网的上行段数据可靠性最高，本数据集即采用该段数据。此类剖面数据不包含光透射率、荧光度以及标量光合有效辐射（scalar par）参数。若需配套使用浮游生物数据，建议仅选用本数据集。 primary链接：该链接将引导用户获取本次航次可用的最优水文测量覆盖数据集。多数情况下，“主版本”数据集为Mark-5型与SEACAT型CTD测站数据的合成集合。此类测站数据已从各自航次文件中提取，并按时间排序。因此，报告的测站编号与站位编号常出现重复，且顺序随机。若存在SeaBird型剖面数据，将以百位数系列测站编号与Mark-5型剖面数据区分，但该命名规则并不统一，且并非所有航次（仅主链接数据集）均遵循此约定。 *编制人：莫琳·泰勒（Maureen Taylor），美国国家海洋渔业局（NMFS）/伍兹霍尔，1996年2月7日 最后更新：2004年11月19日；gfh*
