Sexual harassment is a common experience for women and those from other underrepresented groups in (white) male-dominated fields such as Science, Technology, Engineering, and Mathematics (STEM). Women are especially vulnerable to sexual harassment during remote scientific fieldwork. To date, most of the limited research on fieldwork harassment has focused on individual experiences. There is an urgent need for research on organizational approaches to fieldwork sexual harassment. This study fills this gap by examining sexual harassment prevention by National Antarctic Programs. It draws on a desktop analysis of 36 National Antarctic Program websites with a focus on the current availability and quality of sexual harassment policies and procedures in expeditioner handbooks/field manuals. Findings show that very few National Antarctic Programs make their expeditioner handbooks/field manuals publicly available (n = 9), and even fewer mention sexual harassment in the documentation or describe how to lodge a complaint (n = 3). This article concludes by offering some reasons as to why National Antarctic Programs may be neglecting this issue. It also provides practical recommendations for developing more substantive content in expeditioner handbooks/field manuals and for building inclusive fieldwork environments for a diverse range of expeditioners.
