Block 185 of Green Canyon is known as Bush Hill and is a well known cold seep with a wide array of tube worms.{{cite book|url=https://books.google.com/books?id=gHDQD9Q5Zb4C&pg=PA249|title=Gulf of Mexico Origin, Waters, and Biota|volume=3|series=Harte Research Institute for Gulf of Mexico Studies Series|first1=Noreen A.|last1=Buster|first2=Charles W.|last2=Holmes|publisher=Texas A&M University Press|year=2011|page=249|isbn=978-1-60344-290-9}} This area was the first place in the Gulf of Mexico where gas hydrates were recovered in piston cores.{{cite web|url=http://www.geographic.org/deepwater_gulf_of_mexico/leasing_activity.html#figure8|title=Leasing Activity: Figure 8.

Additionally, like most of the Gulf of Mexico, there is a significant amount of salt tectonics.
Blocks in this protraction area are defined in UTM zone 15 north in feet.{{cite web|url=http://www.gomr.boemre.gov/homepg/pubinfo/MapsandSpatialData.html|accessdate=2011-08-30|title=Gulf of Mexico: Maps and Spatial Data|url-status=dead|archiveurl=https://web.archive.org/web/20110823081500/http://www.gomr.boemre.gov/homepg/pubinfo/MapsandSpatialData.html|archivedate=2011-08-23}}
Climate
As recorded by a station in Block 184, the air above Green Canyon has a tropical rainforest climate (Köppen climate classification Af), with warm winters and extremely oppressive summers and very low diurnal temperature variation year-round (especially in summer), expected for its location far from any landmasses. Experiencing the purest Gulf influences possible, Green Canyon's summer nighttime low temperatures are some of the highest on Earth for any non-arid location, at least counting those on land. Temperatures below freezing are unknown.
The hot, humid air and warm water during summer and autumn can facilitate the development and sustainment of tropical cyclones, specifically Atlantic hurricanes, the water having surface temperatures above {{convert|26|C|F|1|abbr=on}}—the typical threshold for tropical development—from May 25 to October 31 on average, and reaching a maximum of {{convert|30|C|F|0|abbr=on}} on August 5. Precipitation is relatively evenly distributed throughout the year, peaking in late summer at the height of the hurricane season, having a secondary peak in winter, and reaching its nadir in late spring.
