Reference excerpt

This expedition was the final of three expeditions on the NOAAS Okeanos Explorer intended to increase the understanding of the deep-sea environment in the Gulf of Mexico. Gulf of Mexico 2018 was a 23-day telepresence-enabled expedition to collect critical information and acquire data on priority exploration areas identified by the ocean management and scientific communities. The goal of the expedition was to use remotely operated vehicle (ROV) dives in combination with seafloor mapping operations to increase the understanding of deep-sea ecosystems and collect scientific information to support future management decisions. The expedition lasted from 11 April 2018 to 3 May 2018.

ROV Dives

15 ROV dives were conducted ranging in depth from 305 to 3,010 meters to explore the diversity and distribution of deep-sea habitats and associated marine communities in the Gulf of Mexico basin. Operations were focused on characterizing deep-sea coral and sponge communities, bottomfish habitats, submarine canyons, shipwrecks, and chemosynthetic habitats such as brine pools, gas seeps, and mud volcanoes. Midwater exploration at depths ranging from 900 to 300 meters were also conducted during two dives to investigate the diversity and abundance of the largely unknown pelagic fauna.

During these dives hundreds of different species of animals, including several potential new species, new behaviors, and numerous significant range extensions were observed. 67 Biological samples (22 primary and 45 associated and commensal taxa) were collected. 13 of the biological samples represented substantial range extensions, and several were new species to science. 12 rock samples were collected for geochemical composition analysis and age-dating. During dives 6 and 7 two new chemosynthetic communities were documented including a brine pool and extinct brine waterfall at Hidalgo Basin and gas seeps at Walker Ridge 488. During the first dive the shipwreck of the tug boat New Hope was explored for the first time and a 3D model of the site was created. The following dive explored an unidentified wooden vessel, a 3D model of the site was created as well. A smaller objective of the dives was to document the extent of deep sea debris in the area. Trash was found 1,600 meters deep and over 275 kilometers off shore.

Outreach The live video feeds of the expedition were shared publicly worldwide with the live video receiving more than 300,700 views via the NOAA Office of Ocean Exploration and Research (OER) YouTube channel. 85 Scientist, managers, and students from 35 institutions in the United States, Japan, Russia, Norway, United Kingdom, and Canada participated as members of the science team through telepresence. The expedition also conducted 16 live telepresence interactions with various groups engaging more than 400 individuals including the Exploratorium, National Aquarium, Boston College, Hawaii Pacific University, London Natural History Museum, and many more.

Worked examples

Example 1 — a first encounter with NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition

Start with the simplest possible case. Write down what NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition

In research: NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 in science, Oceanographic expeditions, so understanding it makes those chapters shorter.
In everyday life: Look for NOAAS Okeanos Explorer Gulf of Mexico 2018 Expedition outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
