Descripción

A more detailed description of the dataset is in this data paper: https://doi.org/10.3897/BDJ.11.e109649中文版本的說明文件請見: https://www.kuroshio.org.tw/newsite/article02.php?info_id=958The eastern waters of Taiwan have been lacking baseline and research data for several years. This study was initiated by Kuroshio Ocean Education Foundation (KOEF) in collaboration with the Turumoan whale-watching company since 1998, collecting long-term ecological data for cetaceans in the inshore of Hualien, eastern Taiwan. This dataset includes 14,270 records of cetacean sightings from June 1998 to December 2025. Collection of cetacean sighting records was paused for one year in 2001 due to budgetary reasons. All of the sighting records were collected by whale-watching boat guides that were trained by KOEF. Following a standardised protocol, guides used a handheld GPS device and cetacean sighting record sheets to document information about the cetacean species identification, location, time, number of individuals, the presence of mother-calf pairs and mixed-species groups and other states of each sighting during a whale-watching tour. The collection of citizen-science data during this period has significantly advanced Taiwan's cetacean baseline data in the study area. Additionally, we make data available to the public in the form of citizen-science, making a substantial contribution to the advancement of ocean scientific research.This is currently the largest dataset of cetacean sighting records in Taiwan (last updated on 2026-02-12). We have also recorded several species on the International Union for Conservation of Nature Red List categorised as "Data Deficient", "Vulnerable" and "Near Threatened". This study is also the first and only long-term study that has documented cetaceans in the study area.If you have any questions about observation records 1998-2021, please contact Chieh-Hsi Hu. For observation records after 2022, please contact Pei-Yuan Pan.

Cobertura geográfica

All of the cetacean sighting data were collected inshore of Hualien, eastern Taiwan, within an approximate range of 20 kilometres from Hualien Port.

Cobertura taxonómica

This dataset contains cetacean sighting records covering 21 different species. Prior to 2015, beaked whales were only recorded at the family level: Hyperoodontidae (Ziphiidae) and both dwarf sperm whale (Kogia sima (Owen, 1866)) and pygmy sperm whale (Kogia breviceps (Blainville, 1838)) were mostly recorded at the genus level: Kogia Gray, 1846.

Orden Cetacea (Whales and dolphins)

Métodos de muestreo

For each whale-watching tour, each ship accommodates one guide trained by KOEF’s cetacean experts to record cetacean sightings. The boat follows a random path until cetaceans are detected and sometimes we also receive sighting reports from other whale-watching boats. While observing cetaceans, the guide documents the location and time of each sighting with a hand-held GPS device, identifies the cetacean species, estimates the number of individuals and confirms the presence of mother-calf pairs and mixed-species groups in the vicinity. Upon returning, the guide fills in the cetacean record sheet, which contains fields included in this dataset. To avoid collecting duplicate sighting data, when there are trips with more than one vessel in the same area, only the data of one ship is recorded within the same trip. Trained volunteers subsequently input the data into a computer for digital storage.

Descripción de la metodología paso a paso:

  1. While leaving Hualien port, the guide records the departure time using a hand-held GPS.
  2. The boat follows a random path until cetaceans are detected and sometimes we also receive sighting reports from other whale-watching boats. When cetaceans appear, the ship slowly approaches. The guide then marks the location and time with a hand-held GPS, identifies the cetacean species, estimates the number of individuals and confirms the presence of mother-calf pairs and mixed-species groups in the vicinity.
  3. When leaving the cetaceans, the guide marks the leaving time with a hand-held GPS. When entering the port, the guide uses the GPS to mark the arrival time.
  4. After returning to the whale-watching company, the guide fills in the cetacean record sheet, which contains fields included in this dataset.
  5. The cetacean record sheets are organised once a month and the information on the data sheets are entered into an Excel spreadsheet file by trained interns, volunteers and guides of KOEF.
