Abstract:
As part of the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS), the SEFSC conducted shipboard surveys of the oceanic waters of the Gulf out to the U.S. Exclusive Economic Zone (EEZ) between 11 August and 6 October 2018. A two independent visual observer teams approach with Distance sampling was implemented to estimate the detection probabilities for marine mammal sightings.

Purpose:
The primary goal was to collect data on the distribution and abundance of marine mammals in the U.S. waters of the Gulf of Mexico (GOM) using visual survey teams and passive acoustic monitoring.

Supplemental information:
Provider's survey code is PC1805.
Perpendicular distance to the animal is not publicly available.
The dataset is accompanied by transect (effort) data which is provided as a separate file.

Sightings included were detected by the flying bridge only or by both the flying bridge and bridge wing teams.

摘要：
作为墨西哥湾海洋评估计划保护物种（GoMMAPPS）的一部分，SEFSC于2018年8月11日至10月6日对墨西哥湾水域直至美国专属经济区（EEZ）的海洋水域进行了船载调查。采用两个独立的视觉观察员团队和距离抽样方法，以估算海洋哺乳动物目击的检测概率。

目的：
主要目标是收集有关墨西哥湾（GOM）美国水域海洋哺乳动物分布和丰度的数据，通过视觉调查团队和被动声学监测实现。

补充信息：
提供方的调查代码为PC1805。
动物垂直距离信息不公开。
数据集附带横切（努力）数据，作为单独的文件提供。
目击记录仅由飞行桥团队或飞行桥和桥翼团队共同检测。
