Water temperature taken by XBT from the research vessel Italica in the Southern Ocean (> 60 degrees South) and Southwest Pacific Ocean (limit-147 E to 140 W) from 2016-12-31 to 2017-01-05 (NCEI Accession 0287163)

Vertical temperature profiles were collected from December 31st 2016 to January 5th 2017 from the research vessel Italica during an oceanographic cruise between New Zealand and the Ross Sea in the framework of the Marine Observatory in the Ross Sea (MORSea) project of the Italian National Antarctic Research Programme (PNRA). Sippican T7 Expendable Bathythermograph (XBT) probes with a vertical resolution of 65 cm and a maximum nominal depth of 760 m were used. The mean spatial resolutions ranges between 15 nm and 20 nm, according to the specific part of the cruise. XBT launches might have been interrupted in case of severe sea and weather conditions. This implies the possible presence of gaps in the sampling. All temperature profiles are quality controlled for consistency between adjacent profiles and through spike editing. Data are provided in TXT format.

本数据集的垂直温度剖面采集于2016年12月31日至2017年1月5日，采集工作依托意大利国家南极研究计划（Italian National Antarctic Research Programme，PNRA）下属的罗斯海海洋观测站（Marine Observatory in the Ross Sea，MORSea）项目框架，在新西兰与罗斯海之间的海洋科考航次中，由科考船"Italica"号完成。本次航次采用赛普康（Sippican）T7型一次性海水温度剖面仪（Expendable Bathythermograph，XBT），该仪器的垂直分辨率为65厘米，最大标称探测深度达760米。根据航次不同区段的具体情况，平均空间分辨率介于15海里至20海里之间。当遭遇恶劣海况与气象条件时，XBT投放作业可能中断，这将导致采样过程中存在数据空缺。所有温度剖面均经过质量管控：通过验证相邻剖面间的一致性，并结合尖峰编辑（spike editing）流程优化数据，确保数据可靠性。最终数据集以TXT格式对外提供。
