Sediment porosity measurements from the continental margin offshore Washington State, USA

This dataset includes sediment porosity measurements from the continental margin offshore Washington State, USA. Samples were collected by the RV Atlantis on AT26-04 (Cruise DOI: 10.7284/900417). Push core and multi-core samples were collected adjacent to heat flow and pore water chemistry measurement locations along a transect from the upper slope to the incoming plate, including seep sites. The study was designed to evaluate the heat flow, fluid flow, and chemical flux distribution across the convergent margin.

本数据集包含美国华盛顿州近海大陆边缘的沉积物孔隙度测量数据。样本由亚特兰蒂斯号科考船（RV Atlantis）在AT26-04航次（航次DOI：10.7284/900417）期间采集。推挤岩心（push core）和多管岩心（multi-core）样本采集于沿上斜坡至俯冲板块断面分布的热流与孔隙水化学测量点附近，包括渗漏点。本研究旨在评估会聚边缘的热流、流体流动及化学通量分布特征。
