THE NESTOR INSTITUTE
The NESTOR INSTITUTE for DEEP SEA RESEARCH, TECHNOLOGY and NEUTRINO ASTROPARTICLE PHYSICS was created by the Greek Government in August 1998, as a small National Lab. It has the legal status of an Independent Research Institute under the authority of the General Secretariat for Research and Technology of the Ministry of Development.
PURPOSE
To exploit the unique characteristics of the, nearby, deepest site (5200 m) in the Mediterranean by hosting Neutrino Telescopes and a Deep Sea Multidisciplinary Laboratory. 
Part of the Institute’s charge is to evolve into an International Laboratory.

LOCATION

The small town of Pylos in the southwest of the Peloponnesse  in the prefecture of Messinia with an annex in the nearby (11 km) village of Methoni (Meudon). Pylos is 280 km from Athens (3.5 hours drive, 2/3 on motorway), 42 km from Kalamata International Airport, 45 km from the Industrial and Port city of Kalamata.

BUILDINGS 

Office and Lab space: The Institute is housed in a spacious (1000 m²) two storey neoclassical building on the waterfront. 
The building has been classified by the Ministry of Culture as a building of special architectural importance and was renovated recently (including central air conditioning).

COMPUTING FACILITY

A cluster of 36 dual Pentium III-based computers (500 MHz) is the backbone of the computer facility (with 36 Gflops, 4 Gbytes RAM, 416 Gbytes HD).

ELECTRONICS FACILITY

Fully equipped electronics lab (analog and digital) as well electrooptical staffed by two full time engineers and one technician.

MACHINE SHOP FACILITIES

The Institute has a complete machine shop. It is located in a nearby industrial building of 900 m² which also serves as an assembly building for various scientific packages to be deployed in the sea. 
Two hyperbaric chambers can test structures (up to 50 cm diameter) with hydrostatic pressure of up to 600 Atm.

DATA HIGHWAY FROM THE DEEP SEA

A 31 km-long deep sea cable with 18 monomode optical fibers is the data highway. One copper conductor can deliver up to 6 kW of D.C. power (the power return is done electrolyticaly via the sea) to the scientific payloads attached at its end (depth 4000 m). 
The sea end of the cable is retrievable in order to change the scientific payload. The cable has been deployed in June 2000. The cable landing is in the counting station in Methoni.

NAVARINO BAY STATION TEST FACILITY

Since June 1998 a test facility has been created at 50 m depth and can be used 350 days per year. 
A 5.5 km long deep sea cable with 12 monomode fibers and one copper conductor joins the Institute building with a junction box at the other end. 
The purpose is that scientific payloads can be tested for long periods in the bay before they are deployed in the deep.

VESSELS

The Institute owns a score of less than 5m long boats plus:
  1.  “DELTA BERENIKE”, a very large (51 m each side) equilateral triangular ballasted platform with a central well. She can keep station at sea to ±20 m. The platform will be equipped with two 20 Tn winches. 
  2. “LYDIA”, a 42 foot (12.5 m) (GRAND BANKS CLASSIC) open sea fast cruiser with two 120 hp diesel motors plus a hydraulic crane for deploying small scientific payloads.
  3. “THALASSOMACHOS”: A 6.2 m open sea fast (40 knots) rigid hull inflatable, equipped with a 150 hp motor. Moreover, Pylos harbor has a host of medium size vessels with cranes plus one large tug-boat.
