Blake Ridge; Blake Ridge, Southeast US Continental Margin
Date: | June 15, 2018 |
Max Depth: | 3424 Meters |
Bottom Time: | 3 Hours 52 Minutes 18 Seconds |
This dive is part of a series that investigate the similarities and differences in community composition among deepwater habitats of the SE US continental margin. The primary objective for this dive is to characterize the distribution and abundance of benthic fauna at depths greater than 3000 m. A comparison of the diversity/distribution of coral and sponge communities across the region and to the broader Atlantic is of particular importance to understanding biogeography and connectivity of communities in the Atlantic. This site was proposed by Peter Etnoyer in support of SEDCI objectives, as an unexplored area with potential habitat suitability for corals and sponges. This region was first mapped during the Extended Continental Shelf initiative (UNH-CCOM/NOAA), which provided excellent bathymetry and backscatter imagery. New information acquired from this dive will improve understanding of biogeographic patterns and related geologic features in the region.

Giant Bedforms
Giant Bedforms; Blake Ridge, Southeast US Continental Margin
Date: | June 16, 2018 |
Max Depth: | 3358 Meters |
Bottom Time: | 4 Hours 31 Minutes 17 Seconds |
Multibeam maps of the area show a zone of irregular, poorly resolved features that may be current-generated bedforms. The objective of working here is to learn about large bedform evolution under current flow. There is uncertainty as to the origin of these bedforms. Roger Flood of Stony Brook, who proposed the dive interprets the irregular topography as bedforms formed by current flow, while others who are studying this area suggest that underlying gas hydrates may cause faulting and seeps, leading to the topography. Hydrates are known to occur in this general vicinity and there could be venting along faults in the area. Prior Alvin dive sites were nearby (1329-1332), but no dives have been made in this portion of the US EEZ.

Date: | June 17, 2018 |
Max Depth: | 1321 Meters |
Bottom Time: | 5 Hours 52 Minutes 57 Seconds |
This dive is part of a series that will investigate the similarities and differences in community composition between deepwater habitats of the SE US continental margin. During this dive, the ROV Deep Discoverer was proposed to explore a rocky feature on the Blake Escarpment, the outer edge of the Blake Plateau offshore the Georgia coast. The dive's primary objective was to characterize the distribution and abundance of benthic fauna at depths between 1200 and 1400 m. A comparison of the diversity/distribution of coral and sponge communities across the region and to the broader Atlantic is of particular importance to understanding biogeography and connectivity of communities in the Atlantic. This site was proposed by Peter Etnoyer in support of SEDCI objectives, as an unexplored area with potential habitat suitability for corals and sponges.

Stetson Mesa South
Stetson Mesa South; Blake Plateau (Million Mounds)
Date: | June 19, 2018 |
Max Depth: | 734 Meters |
Bottom Time: | 6 Hours 35 Minutes 35 Seconds |
This dive is part of a series that investigates the similarities and differences in community composition between deepwater habitats of the SE US continental margin. The site was proposed by Tom Hourigan (NOAA Deep Sea Coral Research and Technology Program) and Matthew Poti (NOAA NCCOS) as an unexplored area with potential habitat suitability for deep sea corals. The ROV Deep Discoverer explored a trio of mound features located approximately 200 km southeast of Jacksonville, Florida. The three adjacent mounds are located directly in the path of the Gulf Stream. Multibeam data shows many mound features at 400-800 m throughout the Stetson Mesa. These mounds appear to be enormous aggregations of deep-sea coral rubble. This area shows high habitat suitability for deep-sea corals in existing models (Kinlan et al. 2013). The region was first mapped during EX-14-03 and acquiring new information will inform biogeographic patterns in the region. Diving in the area provides important information to groundtruth these models.

Stetson Mesa North
Stetson Mesa North; Blake Plateau (Million Mounds)
Date: | June 20, 2018 |
Max Depth: | 788 Meters |
Bottom Time: | 5 Hours 16 Minutes 55 Seconds |
This dive is part of a series that investigates the similarities and differences in community composition between deepwater habitats of the SE US continental margin. The general area was proposed by several scientists representing the SAFMC, NOAA DSCRTP, NOAA NCCOS, BOEM and the Deep Search team, as this region is an unexplored area with strong potential habitat suitability for deep sea corals. High resolution multibeam bathymetry shows many mound features at depths ranging 400 to 800 m throughout the Stetson Mesa. The dive site was selected for its steep slopes and overall vertical relief, in order to compare deeper areas with those at the mound's crest where current flow is greatest. This area also served as an excellent comparison to mounds explored to the south on the previous dive (Dive05). The area known as Stetson Mesa shows high habitat suitability for deep-sea corals in existing models (Kinlan et al. 2013). The region was first mapped during EX-14-03 and acquiring new information will inform biogeographic patterns in the region. Diving in the area provides important information to groundtruth these models.

Richardson Ridge
Richardson Ridge; Blake Plateau
Date: | June 21, 2018 |
Max Depth: | 873 Meters |
Bottom Time: | 3 Hours 36 Minutes 40 Seconds |
This dive site was selected for its knife-like ridge at the top of a steep 100 m relief slope that had gradients exceeding 30 degrees. Its position on the outer edge of the Gulf Stream's flow raised the question if it was of biogenic (i.e., coral rubble mound) or geologic (erosional scarp of rock layers) origin. The previous 2 dives explored mound features, revealing origin from massive accumulation of stoney coral skeletons. All 4 mounds explored hosted dense living coral and sponge communities. The Richardson Ridge was explored to compare biological communities on the ridge's slope (in the lee of the Gulf Stream) to those on the ridge crest, and to compare these areas with those of the previous 2 dives. This dive was part of a series that investigates the similarities and differences in community composition between deepwater habitats of the SE US continental margin. This site is within a large under-explored area of the Miami Stetson CHAPC and is a high priority region for the Deep Search project, with the primary objective to identify presence / absence of deepwater corals and benthic communities in areas with the potential for offshore development. This area was first mapped during EX-18-05. New information will inform biogeographic patterns in the region, critical for refining habitat prediction models. Diving in the area will provide important information to groundtruth these models.

Cape Fear
Cape Fear; Blake Plateau
Date: | June 24, 2018 |
Max Depth: | 454 Meters |
Bottom Time: | 7 Hours 2 Minutes 43 Seconds |
This dive is part of a series that investigates the similarities and differences in community composition between deepwater habitats of the SE US continental margin. This site is within Cape Fear Lophelia Banks Deepwater MPA. The general area was proposed by the Deep Search team, to identify presence / absence of deepwater corals and benthic communities in areas identified as having oil and gas potential in the Atlantic. Also, the Deep Sea Research and Technology Program and the NOAA Ocean Acidification Program will use information from this dive for future cruises when they will be sampling a number of locations in this area with the objective of fully constraining the carbonate chemistry of the area. Obtaining seafloor video footage at the same area could improve our understanding of the relationship between deep coral communities and carbonate chemistry. This region was first mapped during a MPA cruise aboard the NOAA Ship Nancy Foster in 2007 (NF-07-02) and new information will inform biogeographic patterns in the region. Diving in the area will provide important information to groundtruth these models.

South of Pamlico Canyon
South of Pamlico Canyon; North Carolina Canyons
Date: | June 25, 2018 |
Max Depth: | 1716 Meters |
Bottom Time: | 6 Hours 2 Minutes 42 Seconds |
This dive is part of a series that investigates the similarities and differences in community composition between deepwater habitats of the SE US continental margin. Submarine canyon sites in the past have been shown to be deep sea coral habitats, particularly in areas of rock/hard-bottom exposure. This site was proposed by Deep Search to represent canyon features that have yet to be explored in detail. The autonomous vehicle Sentry has surveyed a handful of locations in the canyons off North Carolina, however visual information about the presence and ID of corals and other benthic fauna have not been possible. An ROV/HOV is required to visually examine these rugged, high profile features. This region was first mapped during a MPA cruise aboard the NOAA Ship Nancy Foster in 2007 (NF-07-02) and new information will inform biogeographic patterns in the region. Diving in the area will provide important information to groundtruth these models.

Date: | June 30, 2018 |
Max Depth: | 521 Meters |
Bottom Time: | 6 Hours 58 Minutes 39 Seconds |
Several hundred seep locations were discovered through multibeam mapping efforts that began in 2012. However, many have not been visually verified. One of the primary goals of the DEEP SEARCH project is to investigate the mid-Atlantic region for chemosynthetic environments in order to identify vulnerable communities that may be adversely influenced by energy exploration. The autonomous vehicle Sentry has surveyed a handful of locations in the canyons off North Carolina, however visual information about the presence of seeps is still necessary. An ROV/HOV is required to visually examine possible seeps along these rugged, high profile features.
