This document discusses data ethics and supporting researchers dealing with ethical issues. It is divided into three parts. Part 1 discusses ethical concerns around data collection, storage, sharing and reuse that technical researchers may face. Part 2 covers privacy issues related to research data reuse. Part 3 proposes infrastructure like workshops, data clinics, and an expanded role for libraries to help support researchers in navigating ethical challenges with their work. The document argues that as data science progresses, support systems are needed to help address new types of ethical issues that may arise.
