Tide Simplified by Phil Clegg Sea Kayaking Anglesey
Tide Simplified By Phil Clegg Sea Kayaking Anglesey Tide is one of those areas that the more you learn about it, the more you realise you don’t know. As sea kayakers, and not necessarily scientists, we don’t have to know every detail but a simplified understanding can help us to understand and predict what we might expect to see when we are out on the water. In this article we look at the areas of tide you need to know about without having to look it up in a book. Causes of tides To understand tide is convenient to imagine the earth with an envelope of water all around it, spinning once every 24 hours on its north-south axis with the moon on a line parallel to the equator. Moon Gravity A B Earth Ocean C The tides are primarily caused by the gravitational attraction of the moon. Simplifying a bit, at point A the gravitational pull is the strongest causing a high tide, point B experiences a medium pull towards the moon, while point C has the weakest pull causing a second high tide. Because the earth spins once every 24 hours, at any location on its surface there are two high tides and two low tides a day. There are approximately six hours between high tide and low tide. One way of predicting the approximate time of high tide is to add 50 minutes to the high tide of the previous day. The sun has a similar but weaker gravitational effect on the tides. On average this is about 40 percent of that of the moon. -

Maine Guide Training
Maine Guide Training 2021 History of Maine Guides ● First hired guides in Maine were Abenaki people who led European explorers, military officials, traders, priests and lumbermen. ● Guiding industry emerged in late 1900s as people in more urban and industrialized regions sought wilderness for recreation ● Cornelia “Fly Rod” Crosby was first guide licensed in 1897; 1700 others were licensed that year. Maine’s Legal Definition of “Guide” Any person who receives any form of remuneration for his services in accompanying or assisting any person in the fields, forests or on the waters or ice within the jurisdiction of the State while hunting, fishing, trapping, boating, snowmobiling or camping at a primitive camping area. Sea Kayaking Guide Specialization Guides can lead paddlesports trips on the State's territorial seas and tributaries of the State up to the head of tide and out to the three mile limit. This classification includes overnight camping trips in conjunction with those sea-kayaking and paddlesports. Testing Process 1. Criminal Background Check 2. Oral Examination ■ Chart and compass work ■ Catastrophic scenario 3. Written Examination (minimum score of 70 to pass) What Maine Sea Kayak Guides CAn Do ● Lead commercial sea kayaking and SUP trips on Maine’s coastal waters ● Lead overnight camping trips associated with these trips (new as of 2005) ● Lead trips with up to 12 people per guide What Sea Kayak Guides CAN’T Do ● Lead paddling trips on inland waters (by kayak, canoe, SUP or raft) ● Take clients fishing or hunting ● Lead trips that require another type of guide license What are the qualities that you most appreciated in guides you’ve encountered? ● Wilderness Guide Association’s Definition of a Guide A trained and experienced professional with a high level of nature awareness. -

Sidemount Diver I (Recreational, OW)
Sidemount Diver I (Recreational, OW) Diver’s Profile: This is an advanced open water diver with some basic experience, having beforehand obtained an Advanced Open Water Diving Certification who wants to further enhance his/her competence as well as his/her distance range by using 2 tanks in sidemount configur ation instead of traditional back- mount configuration, but still in open water. Another reason might be medical considerations (i.e. lumbar disc herniation) Aims & Objectives of the course: This course is designed to expose the advanced OW - diver to alternative cylinder and harness configu- rations when back - mounted cylinders are not appropriate or available or usable . Though considerably more complex than standard back - mount diving, side - mount has clear advantages. Only the side mount diver is truly self - reliant. But, the inherent gas management, trim and complexity of diving in- dependent cylinders present a challenge to even the most experienced back - mount diver. This course - and competence level is a mandatory prerequisite for Sidemount Diver II (OW ). Content: Safety practices, procedures, conservation, gas management, equipment modification/philosophy, trim, streamlining, finning techniques, problem management, task loading, psychological aspects and how to build a "sidemount rig" , air - sharing. Training is strictly limited to the OW environment! Course Classification: The Sidemount Diver I Course is a BASIC and purely RECre - ational specialty diving course. Prerequisites and Requirements: a) Prerequisites Age: 16 years OW - certificate: CMAS 2star Diver or equivalent (fulfilling EN 14153 - 2) Number of previous OW - dives: 25 of which 5 must have been made within 2 months prior to course Other mandatory prerequisites: valid medical attest (fitness for diving), not older than SCD rules or national legislation require (mostly <=1year) Other recommended certificates: CMAS Nitrox Diver or equivalent, Stage Tank Handling Course Further requirements: Equipment as requested under “Personal equipment” b) Course duration and structure Min. -

Enon Valdez Oil Spill Restoration Project Final Report Site Specific Archaeological Restoration at SEW-440 and SEW-488 Restoration Project 95007B Final Report Linda Finn Yarborough United States Department of Agriculture Forest Service Chugach National Forest 3301 C St., Suite 300 Anchorage, Alaska 99503 October 1997 Site Specific Archaeological Restoration at SEW440 and SEW488 Restoration Project 95007B Final Report Siw:The project effort was initiated under Restoration Project 94007B.An annual progress report was issued in January, 1995 by Yarborough, L., under the title Restoration ~ -1995. Theproject continued under Restoration Project 95007B, the subject of annual this report. A second progress report was prepared in September 1995 by Yarborough, L., under the title 1s Reuort. Seutember 1995. FY 95 wasthe last field season for this project. Data analysis and project report preparation took place in FY 96 and FY97.Papers were prepared for presentation and peer reviewed publication, and results were presented to the public in FY 97. Abstract: Project 94007 provided for restoration of two archaeological sites damaged during the Exxon Vuldez Oil Spill and its subsequent cleanup program. Test excavations were carried out at both SEW-440 and SEW-488 during 1994. Analysis and completion of excavations at SEW-488 took place in 1995. Analysis continued in 1996 and 1997. Each site was assessed in the field and mapped prior to testing. Data recovery work yielded both environmental and cultural information. Both sites appear to have been intermittently occupied, SEW-440 over a period of almost 2000 years, and SEW-488 for up to 3000 years. Artifact and zooarchaeological analyses resulted in information on prehistoric technology, subsistence, seasonality and site use. -
Tidal Theory
TIDAL THEORY By Phil Clegg, Sea Kayaking Anglesey Tide is one of those areas that the more you learn about it, the more you realise you don’t know. As sea kayakers (and dinghy sailors) and not necessarily scientists, we don’t have to know every detail but a simplified understanding can help us to understand and predict what we might expect to see when we are out on the water. Causes of Tide To understand tide it is convenient to imagine the earth with an envelope of water all around it, spinning once every 24 hours on its north-south axis with the moon on a line parallel to the equator. Moon Gravity A B Earth C Ocean The tides are primarily caused by the gravitational attraction of the moon.

One way of predicting the approximate time of high tide is to add 50 minutes to the high tide of the previous day. The sun has a similar but weaker gravitational effect on the tides.

The main importance of the sun is the effect of either reinforcing the moon’s force or reducing it depending on their positions relative to each other. -
Rescue Knot Efficiency Revisited
Rescue Knot Efficiency Revisited By John McKently From the 2014 International Technical Rescue Symposium (ITRS) John McKently has been the Director of the CMC Rescue School since 1995 and is a long time ITRS attendee and presenter. In addition to his teaching duties, his practical rescue experience comes from 40 years as a member of the Los Angeles County Sheriff’s Montrose Search and Rescue Team. OCCUPATION / AGENCIES 1. Senior Instructor: California State Fire Training • Confined Space Technician 2. Instructor: California Peace Officer Standards and Training (POST) • Search Management and Winter Search Management 3. Instructor: US Mine Safety and Health Administration (MSHA) 4. Member: Montrose (CA) Search and Rescue Team, Los Angeles County Sheriff’s Department 5. Member: California State Fire Training • Rope Rescue Technician Curriculum Development Working Group • Confined Space Technician Working Group Rescue Knot Efficiency Revisited In 1987 personnel from CMC Rescue performed tests on a variety of knots commonly used in rescue systems to determine their efficiency. The purpose of testing was as preparation for the First Edition of the CMC Rope Rescue Manual and for presentations at various industry events. Prior to this time there had been similar testing on climbing knots, but the rope used was three-strand laid rope (Goldline) and there were no details of the testing conditions or methods used, so the results were not considered repeatable or of unknown value to rescuers using low stretch ropes. Our testing was done at Wellington Puritan, a large rope manufacturer in Georgia, but no details were given about their test machine. There wasn’t any Cordage Institute #1801 standard for test methodology at the time, though the report does state that Federal Test 191A Method 6016 was used.
