Meeting starts at 7:30 p.m.
(Every 3rd Tuesday of every month except December)

September Meeting:

Normal Meeting sequence is as follows:
• Introduce visitors.
• Present Specific Club Information.
• Identify dive events upcoming or planned.
• Identify & discuss diving related news important to divers.
• Present any Show & Tell.
• Attendees speak about current diving experiences or lessons learned.
• Open session.

Thanks to everyone who participated the clubs annual picnic and extra “THANKS” to Larry & Jeri, Ken & Lucy, and Lee & Nancy for supplying the grills, purchasing the steak & chicken, doing the cooking, bringing setup tables, and securing the area. It is very much appreciated.

Review of MUD club paper work indicates that we need Membership (application) Forms and Waivers completed for a number of individual’s. Forms will be available at the club meetings. If your status has changed you may review your form and update it.

As a side note, of 60 Mud Club Surveys sent out in August we had a return rate of 12%. Surveys will be available at the next club meeting.

Last Meeting Highlights:

There were 22 members and 1 visitor (Matt from DL Divers”) in attendance at the August meeting where the following was discussed:

• Phone directory pending identification of paid members.
• MUD Club Picnic, in Niles Aug 22, cooking begins at 12:00 P.M. Identified volunteers for grills, purchasing steaks & chicken, and staking out an area.
• Club cards distributed to members present who had not received any.
• Lesson Learned: Discussed BC weighting- Lake vs River diving.
• Trivia quiz on Niles bridge construction & local effects of pile installation.
• Discussed MI invasive species: Fish & vegetation, and red algae blooms.
• Kevin spoke a little about the JV Moran, Muskegon, the wreck F.W.Wheeler and the City of Green Bay.
• MSRA has been active; R. Wilbanks & Clive Cussler were out looking for “Flight 2501” and located a houseboat.
• Wreck Dive Week – Identified who was going and when.
• Still no update on receiving Sponge Survey kits.
• No show and tell.
• Dives performed included: Havana A &B, Mack’s Wreck, Sass Dives, Rockaway, City of Green Bay and AA5.
• Roma’s afterward 

2015 Dive Schedule:

Organize a dive and paste it on the Facebook MUD club site.

Thirsty Thursdays: The Niles River has provided many Muddies lots of adventures and bottles the last 4 weeks. As its getting dark earlier, you need to be putting a light on your float. Come on down and join the fun.

Seven Mistakes Divers Make & How to Avoid Them

1. Neglecting Health and Fitness
2. Neglecting Proper Gear Maintenance
3. Insufficient Dive Planning
4. Lack of Buoyancy Control
5. Diving Beyond Your Training
6. Running Out Of Air
7. Not Taking Personal Responsibility

Lack of Buoyancy Control

It’s not surprising that the most common injuries among divers are related to buoyancy issues — barotrauma, uncontrolled ascents, marine life injuries and more could be prevented with some practice and attention to detail.

Inefficient buoyancy control can result in descending deeper than planned, altering the intended dive profile and potentially increasing air consumption. Constant adjustments to your buoyancy control device can also affect air consumption.

The worst case scenario is an uncontrolled ascent, which places the diver at risk for a lung overexpansion injury (pulmonary barotrauma) and substantially increases the risk for an arterial gas embolism.

Ear injuries are also commonly associated with ineffective buoyancy control. During descent, if you feel uncomfortable pressure in your middle ears or sinuses, you should stop your descent, ascend until the pressure resolves, attempt to equalize and, if successful, continue to descend. If you experience a reverse block on ascent, you should descend a bit and attempt to equalize. These procedures are difficult to execute without proper buoyancy control.

Most marine life injuries result from unintentional contact between a diver and the marine life. Proper buoyancy control is essential to protect ourselves and the environment.

The physics of descending and ascending require conscious adjustment based on exposure protection, dive environment and choice of equipment.

Buoyancy Control Begins with Proper Weighting

The amount of weight you select should allow you to descend, not make you sink. Pre-dive buoyancy tests are a crucial tool in determining proper weighting.

Calculating weight requirements: Different exposure suits, dive environments (saltwater vs. freshwater), and tank size and composition (steel vs. aluminum) require different amounts of weight to attain proper buoyancy.

Your BCD is not an elevator. Be aware of how your BCD responds to the addition or venting of small amounts of air.

And remember, buoyancy changes during the dive. On descent, your wetsuit compresses decreasing buoyancy. During the dive, as the gas in your tank is depleted, the tank becomes more buoyant. On ascent, the air in your wetsuit and BCD expands, increasing your buoyancy.

The benefits of buoyancy control are definitely worth the investment of time, maintenance, and practice to enhance your diving and to help you avoid injury.

When is the last time you made practiced assisting a disabled diver? Have you ever thought on how you would respond while diving the river?

When in doubt, don’t – Be safe out there!
