Scientific cables are those submarine cables that have are being used for various scientific research purposes. These cables can be ones that are currently carrying traffic or that have been retired from service. However protection of these cables is just as important as for the commercial cables since important research and data collection relies on them.

Cables in Powered Scientific Use: |
|
|
ATOC-Kauai (Barking Sands, Kauai, Hawaii to offshore) |
This cable runs
from the US Navy Pacific Missile Range Facility (PMRF) at Barking Sands
clockwise around the island, ending at a point 800 m deep on the north slope.
The cable is used to connect an acoustic transmitter to shore in support
of the ATOC project (Acoustic Thermometry of Ocean Climate; see http://atoc.ucsd.edu/).
Transmissions to receivers around the Pacific were used to demonstrate
the ability to measure large-scale ocean temperature acoustically.
This work is continuing as part of the Office of Naval Research funded
North Pacific Acoustic Laboratory (NPAL; http://npal.ucsd.edu). |

HAW-4 (Makaha to 23oN) |
The Hawaii end of the retired first-generation fiber-optic HAW-4 cable is now being used for the ALOHA Cabled Observatory (ACO; http://aloha.manoa.hawaii.edu). The shore station is at Makaha and the ACO node is at Station ALOHA (22 45N, 158W, 4728 m water depth) about 100 km north of Oahu (237 km cable length). The remaining portion of the cable is still connected in California at the Point Arena Cable Station. The ACO provides ~1000 W, 100 Mb/s and 1 us timing to ocean science instruments on the seafloor and in the water column. The ACO provides the infrastructure to support on-going science projects, complementing the Hawaii Ocean Timeseries (HOT) program that has been collecting data at Station ALOHA since 1988.

Cables in Unpowered Scientific Use: |
|
|
NPS Pt Sur
(Point Sur to Sur Ridge, 50 km) |
A retired US Navy acoustic cable with a
bottom mounted acoustic receiver on the seaward end. It is operated by the Naval Post-graduate School (NPS; see http://www.oc.nps.navy.mil/~icon/frames/acoustic_frame.html).
The acoustic receiver is used for ATOC (receiving signals from an
acoustic transmitter off Kauai), local acoustic tomography experiments, and
ambient sound studies. This is an armored submarine cable, 3.2-inch outside diameter
and 50 km long. |
