Thermohaline staircase interface networking detection method resource, Arctic Ocean, 2024

The resource contains pseudocode and MATLAB code for the interface networking detection method (NDM). This method was used for systematic detection and specification of diffusive convective and salt fingering staircases in upper Arctic Ocean conductivity, temperature and depth (CTD) data.
The method was developed over 2021-2024 for statistical analysis of staircase tendencies, seasonal variation, and regional disparities in the major Arctic Ocean basins and their over slopes. The changing upper Arctic Ocean hydrography, especially over the eastern side recently, has significant climate implications and correlates with changes in the staircase occurrence and properties. The method operated on data sets from profiler instruments belonging to the Nansen and Amundsen Basins Observational System (NABOS) project and Ice-Tethered Profiler (ITP) program. This data comprised of temperature and salinity profile records. The method employs a novel interface networking (graphing) process for extracting staircases from noise.
The principal resource is the pseudocode and program code in the NDM_algorithm.pdf file. Program and data files are also provided for a demonstration and for code scavenging. The resource files by no means contains a release distribution; the program code is developmental and undocumented.

本数据集包含界面网络检测法（Interface Networking Detection Method, NDM）的伪代码与MATLAB代码。该方法用于系统检测并刻画北极上层海洋导电率-温度-深度（Conductivity, Temperature and Depth, CTD）数据中的扩散对流与盐指阶梯结构。
本方法于2021至2024年间开发，用于统计分析北极主要海盆及其斜坡区域内阶梯结构的演化趋势、季节变化与区域差异。
北极上层海洋水文状况的变化（尤其是近期东侧海域的变化）具有重要的气候意义，且与阶梯结构的出现频率及特征变化密切相关。
本方法依托南森-阿蒙森海盆观测系统（Nansen and Amundsen Basins Observational System, NABOS）项目与冰系锚定剖面仪（Ice-Tethered Profiler, ITP）计划的剖面仪数据集开展工作，所用数据包含温度与盐度剖面记录。
该方法采用一种新颖的界面网络（绘图）流程，从噪声背景中提取阶梯结构。
本数据集的核心内容为NDM_algorithm.pdf文件中收录的伪代码与程序代码，同时还提供了演示用程序与数据文件，可供代码复用参考。
本数据集文件并非正式发布版本，所用程序代码尚处于开发阶段且未进行文档化处理。
