Supervised Dive
EFFECTIVE 1 March 2009 MINIMUM COURSE CONTENT FOR Supervised Diver Certifi cation As Approved By ©2009, Recreational Scuba Training Council, Inc. (RSTC) Recreational Scuba Training Council, Inc. RSTC Coordinator P.O. Box 11083 Jacksonville, FL 32239 USA Recreational Scuba Training Council (RSTC) Minimum Course Content for Supervised Diver Certifi cation 1. Scope and Purpose This standard provides minimum course content requirements for instruction leading to super- vised diver certifi cation in recreational diving with scuba (self-contained underwater breathing appa- ratus). The intent of the standard is to prepare a non diver to the point that he can enjoy scuba diving in open water under controlled conditions—that is, under the supervision of a diving professional (instructor or certifi ed assistant – see defi nitions) and to a limited depth. These requirements do not defi ne full, autonomous certifi cation and should not be confused with Open Water Scuba Certifi cation. (See Recreational Scuba Training Council Minimum Course Content for Open Water Scuba Certifi ca- tion.) The Supervised Diver Certifi cation Standards are a subset of the Open Water Scuba Certifi cation standards. Moreover, as part of the supervised diver course content, supervised divers are informed of the limitations of the certifi cation and urged to continue their training to obtain open water diver certifi - cation. Within the scope of supervised diver training, the requirements of this standard are meant to be com- prehensive, but general in nature. That is, the standard presents all the subject areas essential for su- pervised diver certifi cation, but it does not give a detailed listing of the skills and information encom- passed by each area. -

The Musculature of the Head of the Corydalus Larva (Neuroptera, Sialidae)
THE MUSCULATURE 0%’ THE HEAD OF THE CORYDALUS LARVA (NEURqOPTERA, SIALIDAE) 1,2 SOL KBAMER * Departmawt of Zoology, University of Wisconsm, Madison, Wisconsin ‘IWENTY-EIGIXT FIGURES The Neuroptera have long been regarded one of the most primitive groups of the holometabolous insects. Crampton ( ’21) considered the Neuroptera an extremely important group from the standpoint of the siudy of the phylogeny of higher in- sects, and emphasized the primitiveness of such forms as Sialis, Corydalus, and Chauliodea among the Neuroptera (Megaloptera). Although he considered the Coleoptera the more primitive of the two orders from a consideration of the head and mouthparts, he emphasized the astonishing similarity between larval Coleoptera and Neuroptera and concluded that the Coleoptera appear to lead to the Neuroptera which in turn lead to the Mecoptera, Diptera and Siphonaptera on the one hand and to the Trichoptera and Lepidoptera on the other. More recently Chen (’46),in a study on the evolution of insect larvae based on a wide series throughout the Holometabola, selected the nenropteroid genus Corydalus as possessing the most primitive or generalized known type of larva. He desig- nated this primitive type by the term “campodeoid-polypod, ’? characterized by having three pairs of thoracic and 10 pairs of abdominal legs, the latter bearing each a vesicle and a stylus. From this study Chen concluded that all existing types of larvae have been (derivedfrom this primitive type in two ways : Corydalus cornutus L. The writer is grateful for the assistance of R. E.

SCUBA DRILLS Snorkeling Gear Prep, Entry, Snorkel Clear, Kicks Gear Prep: Mask (Ant Fogged) –Fins, Gloves, Boots, Ready by Entry Point Access
(616) 364-5991 SCUBA DRILLS WWW.MOBYSDIVE.COM Snorkeling Gear Prep, Entry, Snorkel clear, Kicks Gear prep: Mask (ant fogged) –fins, gloves, boots, ready by entry point access. (it is crucial that the mask-fins-boots are properly designed and fitted before the aquatic session to prevent delays in training due to gear malfunction ) Equipment nicely assembled by entry point for easy donning and water access ENABLED EQUIPMENT NICELY ASSEMBLED – BUDDY CHECK – LOGBOOK CHECK – ENTRY – DRILL REVIEW Equipment Nicely Assembled: (Each Diver needs to develop the practice of properly assembling their scuba gear by themselves) Full tank secured until ready for gear assembly. Tank upright, BCD tank band straps are loosened as to allow easy placement of strap around the tank. NOTE: Hard pack BCD’s usually have ONE tank band, Soft pack BCD’s usually have TWO tank bands. Most bands have a buckle / cam strap and need to be weaved a particular way to stay secured. Ensure the BCD’s placement on the tank so the tank valve is level with where the diver’s neck will be and that the front part of the valve (where the air is released) is facing the back of the diver. Secure the strap or straps so they are tight enough to pick up the BCD and tank and not slip while shaking. Regulator placement: The First stage (dust cap removed) is placed over the tank valve so the intake of the 1st stage covers the o-ring on the tank valve, (o-ring should be in place – if not, lack of seal will cause air leak). -
Snorkels: Pros and Cons!
Snorkels: Pros and Cons! The snorkel has been considered a standard piece of diving equipment for decades. It provides the simple but useful ability to swim face down on the surface without having to lift your head to breathe. Snorkels can also conserve compressed gas for the dive and help minimize accidental water intake in rough waters when breathing through the regulator is not an option. The impact of snorkels is not all positive though. They are a source of drag in the water, which is not a good thing when they tug on the mask, a decidedly critical piece of equipment. They can also be a source of entanglement, for example, with kelp or hair. And they can be incompatible with some equipment configurations. So, what to do? Pro position: A snorkel provides an option that can be helpful in normal situations. This is a straightforward argument. When a snorkel is needed it is likely to be needed quickly, so having it readily available is a valid choice for preparedness. Con position: The need for a snorkel is low when carrying ample gas supplies or on sites where surface swimming is unlikely, where entanglement is likely (wrecks or caves), or where they offer little utility (ice or caves). The irritation of it getting in the way when hanging from the mask also makes it less desirable. Where to Put It? Since the hose for most open-circuit regulators comes over the right shoulder, a snorkel is usually least intrusive if mounted on the left side of the mask. Closed-circuit equipment has large hoses on both sides of the head, so keeping the snorkel in a pocket or pouch is likely the best option. -
Aquatic Insects and Their Potential to Contribute to the Diet of the Globally Expanding Human Population
insects Review Aquatic Insects and their Potential to Contribute to the Diet of the Globally Expanding Human Population D. Dudley Williams 1,* and Siân S. Williams 2 1 Department of Biological Sciences, University of Toronto Scarborough, 1265 Military Trail, Toronto, ON M1C1A4, Canada 2 The Wildlife Trust, The Manor House, Broad Street, Great Cambourne, Cambridge CB23 6DH, UK; [email protected] * Correspondence: [email protected] Academic Editors: Kerry Wilkinson and Heather Bray Received: 28 April 2017; Accepted: 19 July 2017; Published: 21 July 2017 Abstract: Of the 30 extant orders of true insect, 12 are considered to be aquatic, or semiaquatic, in either some or all of their life stages. Out of these, six orders contain species engaged in entomophagy, but very few are being harvested effectively, leading to over-exploitation and local extinction. Examples of existing practices are given, ranging from the extremes of including insects (e.g., dipterans) in the dietary cores of many indigenous peoples to consumption of selected insects, by a wealthy few, as novelty food (e.g., caddisflies). The comparative nutritional worth of aquatic insects to the human diet and to domestic animal feed is examined. Questions are raised as to whether natural populations of aquatic insects can yield sufficient biomass to be of practicable and sustained use, whether some species can be brought into high-yield cultivation, and what are the requirements and limitations involved in achieving this? Keywords: aquatic insects; entomophagy; human diet; animal feed; life histories; environmental requirements 1. Introduction Entomophagy (from the Greek ‘entoma’, meaning ‘insects’ and ‘phagein’, meaning ‘to eat’) is a trait that we Homo sapiens have inherited from our early hominid ancestors. -
Snorkel Mask Instruction Manual Preparation
Snorkel Mask Instruction Manual ENGLISH Preparation: It is helpful to clean the mask before each use to remove any residue. A new diving mask may also contain silicone residues from the manufacturing process. Apply a small blob of mild toothpaste to the inside of the mask and brush gently in circular movements. Rinse the mask and dry it with a cloth. Repeat the procedure if necessary. When the mask is clean and ready to use, attach the snorkel. Make sure the snorkel is free of dirt and air can enter the mask. Seal check: Pull the mask straps over your head and check that the mask fits well on your face. Continue to breathe normally to see if it is leaking. If you feel a slight pressure while breathing, the mask will fit perfectly. If the mask does not fit properly, air circulation may be impaired and the inside of the mask may fog up. If it is too tight or too loose, remove the mask and adjust the straps properly. (DO NOT ADJUST THE STRAPS TOO TIGHTLY!). It is best to remove any facial hair as it may affect the fit of the mask and cause it to leak. Use: When you are in the water, stay on the surface and breathe evenly through your nose or mouth. If you begin to feel dizzy, remove the mask immediately. Breathing with the tube works best when you lift your chin slightly. If water enters the mask, head to the surface and the water will run out of the valve on the chin by itself. -
