Drysuits - Neoprene
Neoprene is a type of synthetic rubber, often also used in neck and ankle seals in drysuits. Neoprene can be specially prepared to contain millions of tiny enclosed air bubbles, forming a buoyant and thermally-insulating material. This is called "foamed neoprene" or "foam-neoprene" (not all neoprene contains foam).
As foam-neoprene tends to shrink over the years as it out-gases and slowly becomes more rigid. An alternative is crushed or rolled neoprene, which is used in the construction of all Northern Diver neoprene dry suits and is less susceptible to volume changes when under pressure, and shrinks less.
Crushed neoprene dry suits provide some insulation by themselves (unlike membrane dry suits), but even with foam dry suits, thermal under-suits are usually worn. With a crushed neoprene suit, less insulation is needed underneath.
The undersuits usually vary from a fine base layer similar to the Northern Diver Thermalskin, up to a thicker layer like the Northern Diver Arctic Base or Metalux Arctic. Some people also use a standard wet suit (worn dry), or polyester fabrics used in mountaineering and other cold weather uses (these may also be in pieces, including vests or sleeveless vests). Such fabrics also ultimately insulate in the same way as foam, using air in which convection is retarded by the small sizes of the air spaces. However, per volume and weight of fabric, the best-insulating dry polyester fabrics are more effective than foam, because their air pockets are smaller.

Fossil Beach | © Unknown
Fossil Beach is located between Mornington and Mount Martha on the Eastern side of Port Phillip. It's not a sandy swimming beach but a narrow rocky beach where fossils are found.
In 1854, geologist A.R.C. Selwyn reported a multitude of fossils in the limestone cliffs in a stretch of rocky bay beach between Mornington and Mount Martha. They showed evidence of Australian sea life from 10-15 million years ago and led to the beach being named Fossil Beach.
Location: Mornington, Victoria 3941
Parking: Car park located opposite 631 Esplanade, Mornington. Follow the walking track from the car park on the Esplanade down to Fossil Beach.
See WillyWeather (Fossil Beach) as a guide for the tide times and the height of the tide.
Boon Wurrung / Bunurong country
Traditional Owners — This dive site is in the traditional Country of the Boon Wurrung / Bunurong people of the Kulin Nation. This truly ancient Country includes parts of Port Phillip, from the Werribee River in the north-west, down to Wilson's Promontory in the south-east, including the Mornington Peninsula, French Island and Phillip Island, plus Western Port. We wish to acknowledge the Boon Wurrung as Traditional Owners. We pay respect to their Ancestors and their Elders, past, present and emerging. We acknowledge Bunjil the Creator Spirit of this beautiful land, who travels as an eagle, and Waarn, who protects the waterways and travels as a crow, and thank them for continuing to watch over this Country today and beyond.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.
The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
