Signature of climate-induced changes in seafood species served in restaurants

Copies of publicly available restaurant menus from Vancouver (Canada), Los Angeles (USA) and Anchorage (USA) dated since the 19th century were collected from the Internet and museum archives. Archives of menus from restaurants in Vancouver collected from The University of British Columbia (UBC) library, Victoria Island University library, the City of Vancouver Archives, and the Museum of Vancouver Archives were surveyed (N = 228). Only menus that have specified a year of publication or a range of years were recorded. The menus were categorized into three different time periods: 1888-1960, 1961-1980, and 1981-1996. In addition, a total of 134 present day (2019 -2021) menus from Vancouver, 72 menus from Los Angeles menus, and 76 from Anchorage were collected online using the restaurants’ websites or other websites where restaurant menus were made available publicly, including TripAdvisor(https://www.tripadvisor.ca/), KAYAK (https://www.ca.kayak.com/), and OpenTable (https://www.opentable.ca/). The name of the restaurant, year and the seafood specified in the name of the dish or food ingredients were recorded if the information was available on the menus.

本数据集采集了来自加拿大温哥华、美国洛杉矶及安克雷奇的公开可获取的餐厅菜单复制品，其年代跨度自19世纪起，采集渠道涵盖互联网与博物馆档案。其中，从不列颠哥伦比亚大学（UBC）图书馆、维多利亚岛大学图书馆、温哥华市档案馆及温哥华博物馆档案馆收集的温哥华本地餐厅菜单档案共计228份，仅收录标注有出版年份或年份区间的菜单。上述菜单被划分为三个历史时段：1888-1960年、1961-1980年及1981-1996年。此外，本次采集还包含2019-2021年的当代菜单：通过餐厅官方网站或其他公开提供餐厅菜单的平台（包括TripAdvisor（https://www.tripadvisor.ca/）、KAYAK（https://www.ca.kayak.com/）及OpenTable（https://www.opentable.ca/））在线收集到温哥华菜单134份、洛杉矶菜单72份、安克雷奇菜单76份。若菜单上包含相关信息，则会记录餐厅名称、年份，以及菜品名称或食材中提及的海鲜品类。
