Sea Ice Melt Pond Data

As part of the Seasonal Ice Zone Observing Network (SIZONET) project monitoring the seasonal ice zone, studies were carried out tracking the evolution of albedo and melt pond coverage during the melt season. The data has enabled us to better understand how meltwater interacts with sea ice to control melt pond formation and evolution [Polashenski et al, 2011]. The series of datasets collected in Barrow, AK as part of that project are archived here. The datasets are each collected at a site selected to represent level first year sea ice. Measurements are collected either along a transect (typically 200m long), or over an area adjacent to the transect (typically 100m x 200m). Several data types, including albedo measurements, LiDAR surface measurements, snow/pond depths, and fractional surface coverage are included. Metadata describing each site, as well as describing the methods of data collection can be found on each site's page. 2008 - This site was set up in April 2008 and monitored from 5/28/08 to 6/17/08. The study included only transect measurements. 2009S - This site was set up in April 2009 and monitored from 5/21/09 to 6/25/09. The study area was 70m x 200m in size. 2009N - This site was set up in April 2009 and monitored from 5/19/09 to 6/25/09. The study area was 100m x 200m in size. 2010 - This site was set up in April 2010 and monitored. 2011 - This site was set up in April 2011 and monitored only briefly in early June.

作为监测季节冰区的季节冰区观测网络（Seasonal Ice Zone Observing Network, SIZONET）项目的一部分，研究团队针对融冰季的反照率与融池覆盖度演化展开了追踪观测。本数据集助力我们更深入地理解融水如何与海冰相互作用，进而调控融池的形成与演化过程[Polashenski等，2011]。本项目在阿拉斯加州巴罗（Barrow, AK）采集的系列数据集现已归档于此。

所有数据集均采自选定的、可代表平坦一年海冰（first year sea ice）的观测站点。数据采集方式分为两类：沿断面（通常长度为200米）采集，或在断面周边区域（通常为100米×200米）采集。数据集涵盖多种类型的观测数据，包括反照率测量、激光雷达（LiDAR）地表测量、积雪/融池深度测量以及地表覆盖占比数据。各站点的元数据（含站点基本信息与数据采集方法）均可在对应站点页面查阅。

2008年：该站点于2008年4月搭建，监测时段为2008年5月28日至6月17日，本次研究仅采用断面测量方式。
2009S：该站点于2009年4月搭建，监测时段为2009年5月21日至6月25日，研究区域面积为70米×200米。
2009N：该站点于2009年4月搭建，监测时段为2009年5月19日至6月25日，研究区域面积为100米×200米。
2010年：该站点于2010年4月搭建并开展监测。
2011年：该站点于2011年4月搭建，仅在6月初进行了短期监测。
