Abstract:
A spring cetacean survey in the northern U.S. Gulf of Mexico was conducted in 2001 by NOAA Southeast Fisheries Science Center and Minerals Management Service to examine cetacean abundances in both oceanic and continental shelf waters.
This survey was conducted in coordination with the spring Southeast Area Monitoring and Assessment Program (SEAMAP) ichthyoplankton survey.

The dataset contains sightings of not only cetaceans but also other species including sea turtles, fish and shark observed during the ship survey.

During the 40 survey days, at least 17 species were sighted, including

Bryde's whale
Sperm whale
Kogia spp.
Cuvier's beaked whale
Striped dolphin
Spinner dolphin
Clymene dolphin
Pantropical spotted dolphin
Atlantic spotted dolphin
Bottlenose dolphin
Rough-toothed dolphin
Risso's dolphin
False killer whale
Killer whale
Pilot whale
Pygmy killer whale
Melon-headed whale

The dataset is accompanied by transect data which is provided as a separate file.

Purpose:
The purpose of this survey is to examine the distribution and estimate abundance of cetaceans in U.S. waters.

Specific objectives of this survey are:

1. Collect ichthyoplankton samples for estimates of the abundance and distribution of Atlantic bluefin tuna larvae.

2. Collect data to estimate the abundance and distribution of cetaceans in the oceanic northern Gulf of Mexico.

3. collect associated environmental data at all designated ichthyoplankton stations and marine mammal sightings.

4. Collect data on the distribution of sea turtles, seabirds and other marine life.

5. Obtain biopsy samples of skin and blubber from selected cetacean species for genetic stock structure and contaminant analyses.

6. Obtain photographs of selected cetacean species for photo-identification studies.

7. Collect data on distribution and type of marine debris encountered during the survey.

摘要：美国墨西哥湾北部海域于2001年由NOAA东南渔业科学中心和矿产管理局联合开展春季鲸类调查，旨在评估海洋及大陆架水域中的鲸类丰度。本次调查与春季东南海域监测与评估计划（SEAMAP）的浮游生物调查同步进行。
数据集包含船载调查期间观察到的鲸类及其他物种的记录，包括海龟、鱼类和鲨鱼。在为期40天的调查中，共观察到至少17种物种，包括布氏鲸、抹香鲸、脊鳍鲸属、库氏抹香鲸、斑纹海豚、旋纹海豚、 Clymene 海豚、热带斑海豚、大西洋斑海豚、瓶鼻海豚、糙齿海豚、 Risso 海豚、伪虎鲸、虎鲸、领航鲸、侏儒虎鲸和鼠海豚等。
数据集附带横切数据，作为独立文件提供。
目的：本次调查旨在探究美国水域中鲸类的分布及丰度估计。
具体目标包括：
1. 收集浮游生物样本，以估计大西洋蓝鳍金枪鱼幼虫的丰度和分布。
2. 收集数据，以估计墨西哥湾北部海域中鲸类的丰度和分布。
3. 在所有指定的浮游生物站点和海洋哺乳动物观测点收集相关环境数据。
4. 收集关于海龟、海鸟及其他海洋生物分布的数据。
5. 从选定鲸类物种获取皮肤和脂肪组织的活检样本，用于遗传种群结构和污染物分析。
6. 获取选定鲸类物种的照片，以进行照片识别研究。
7. 收集调查期间遇到的海洋垃圾的分布和类型数据。
