Hi miss mel I watched your video last year before writing my exam &now I'm writing again doing revision ,Thank you so much you simplify it &make it easier &better ,God bless you !❤
Hi Miss Mel, I’m also from South Africa and i was really struggling to get a Geography tutor but i watched your videos and they really helped!!!! I also saw the maps you use are the same as mine so i knew you were from SA.Thank you so much 😊Please continue making more Geography videos they really help!!!
Because of the coming micronova, declination is moving much farther, and much faster and so declination information is likely incorrect My up-to-date declination is 30 degrees, 15 degrees off from the official declination for my area. but there is still a way to recalibrate magnetic declination using the shadow of sticks recording the path of the sun---rotation of the earth has not yet changed. First stick will show East. Mark it with a sharp stick pushed in. After a few minutes you can mark sun shadow travel where the shadow has moved - Push another stick in to mark West. Lay a straight stick from the E mark to the W mark. Geographic north or True North is 90 degrees from the E-W line. With your compass pointing toward True North, note how far off your compass is now. That is your true up-to-date declination. More on micronova in my 2nd book, Surviving the Micronova: This Train Is on the Tracks is available now.
omg Miss Mel , tysm for thee help. my geography teacher expects us to know everything and she never ever explains anything. you are truly a life safer.
Hii Mam am from SA and thank you so much for the video's I've been struggling with map work since the beginning of the year and I've been watching videos to understand but once I bumped with yours I understood within a minute thank you so much I'm confident enough to go and write my geography examination knowing that I lack nowhere ❤️Thank you so much and God Bless You Keep on Doing the Videos ❤❤lots of love
Thanks for your comprehensive explanation. Just had one question: What happens if your Mean Magnetic Declination is EAST of TN (IE: 23*50' E of TN) and the mean annual change is EAST (6' E of TN)? Do you still ADD to the WEST and SUBTRACT to the EAST?
As far as I know, yes. I've tried to research it, but I don't seem to come across any difinitive answer. I think the thing to focus on is the mean annual change direction. Add for west, subtract for east, because the anchor point is still true north, regardless of the mean magnetic declination direction. But I'll be honest - I've never seen a calculation like that, and so I could be mistaken. Great question though! Let me know if you come across a solid answer 👍
@@MelTeaches Thanks for the response. It's been years since I've done Geography in high school in RSA so this question might deviate from the material students need to pass exam. The add west and subtract east ("mnemonic" - 1:43 ) only applies to west declination from what I can see (South African exams all have west..?). I've bushing up on compass nav (and live in Australia with easterly declination) so needed practical usage of adjusting for variation. Found this UA-camr (Mark L - 101 Magnetic Variation) that lays it out pretty well (and uses the degree function on his calculator to add degrees & minutes as a bonus which might help some of your viewers confirm their calculations). Hope this helps 😁👍.
Thank you Ma this video is very helpful to me. Pls can you help us do another similar video with different examples in year and a given month from the map and also conversion factor 🙏
@@sc7244 That's awesome man. I've been fighting tooth and nail to get a spot but unfortunately I'm a reservist and my unit gets jackshit. I shifted my focus to latvia for now and when I get back I'm going to transfer to reg force and then go for recce
you are a great teacher ,will you please elaborate more on mapwork calculations, i struggle a lot...am writing final exams sooner ..with this one ...i got it😘...true north and bearing calculations please
Thanks for this. I live on the West coast and my chart reads 020E 1999 (7W). So I think I should multiply 7 by 25 and SUBTRACT in this case because the declination is E and the annual correction is W.
West is + and East is - if we go from the meridians of the map to the compass bearing. If we go from the compass to the map, it is the other way around.
Hyy Mel.... please help me but use this information because it is confusing and what's lot of converting "Mean magnetic declination 16° 45' west of True North (July 2002).mean annual change 7' westwards (2000-2005) supplied by Hermanus magnetic observatory.
This is so interesting 🤔 how about if you want to do 2023 but I don't have a 🗺️ now what if I don't have a map but I just want to do 2022 with 2023 is that possible
Hey Ms Mel Your videos have been so helpful... I always hated Geography but you made me love it for some reason no teacher has made me enjoy Geography like you do... trust me I'm smelling an A+🤍💞🦋
So if I do 83' ÷ 60 = 1.383333333 I now know I should add 1° So I can do 1.383333333 - 1 = 0.383333333 and than simply do 0.383333333 × 60 = 23 for the Minutes....
really? 9 minute video on how to adjust for declination? step 1: get the angle of magnetic north to true north (you don't have to calculate it - it's given online...) step 2: find out if the magnetic north is to the left or right of the true north from where you are on the earth (again, already figured out - all you have to do is look online) step 3: if it's to the left of true north, move the dial to the right at the angle calculated... if it's to the right of true north, move the dial to the left at the angle calculated... example: i live in calgary...the position of magnetic north is approx 16 degrees right of true north...therefore i just more the dial to the left 16 degrees (it will be minus because the numbers go up clockwise) - at 300. moving it 16 to the left is just moving to 284... all the videos with complicated explanations for a simple calculation... oh, and i have a degree in astrophysics so i understand why magnetic north behaves as it does - and it didn't help worth crap because i just overcomplicated it like everyone else... just make it easy...

Hey We have the same first name!!!! (Irl) so cool I'm also from South africa

I am a teacher and I'm gaining more knowledge by watching you and you are the best of the best 🎓🎓🎓
Good instruction. As an educator I enjoyed the pace and delivery. Well done.

Thank miss Mel, All the way from Hermanus, South Africa ❤☺️
Amazing explanation thank you. Greeting from Iraq
This video is clear, precise and very useful.
You're God sent😙this helped me for my last minute preps for today's exam❤ Thank you Mel
This is a very good explanation of explaining an obscure, but important topic.
You deserve more subs Mel, thx
She explains better than my geography teacher❤
What if the annual change is having a negative sign with decimal like -5.5

Perfect, I’m going on a recon course and needed a refresher. Good video! Cheers
I see that canadian flag in your bio. Basic recce patrolman?
@@3User Yeah buddy
@@sc7244 How was it? Trying to get on it myself.

How to calculate if it's eastwards
u subtract
This was very helpful
Wow that's excellent
Please do map distance
Well done
Hyy Mel.... please help me but use this information because it is confusing and what's lot of converting "Mean magnetic declination 16° 45' west of True North (July 2002).mean annual change 7' westwards (2000-2005) supplied by Hermanus magnetic observatory.

Hey Ms Mel
Your videos have been so helpful... I always hated Geography but you made me love it for some reason no teacher has made me enjoy Geography like you do...
trust me I'm smelling an A+🤍💞🦋
Thank i got hope of studying online .. but i didnot trust before
Do this with a easterly declination change
Gradient please
thank youuu
if you take u 83 and divide by 60 u get 1.38 push the degree button on calculator by the b or fact and bamm in a genius
I wish i had teacher like you at school :p
Thank for every thing , that was so helpful 🌷
what is the magnetic declination of north magnetic today ?? what degrees ?
Thank u very much
So if I do 83' ÷ 60 = 1.383333333 I now know I should add 1°
So I can do 1.383333333 - 1 = 0.383333333 and than simply do
0.383333333 × 60 = 23 for the Minutes....
Hi mama please do true north calculating
From the second example at the final answer how did you get the 25°?
From the 24° 83'. That 83' is actually 1°23'. So the answer becomes 24° + 1°23' or 25° 23'.
None of that information was on my map.
I love you
really? 9 minute video on how to adjust for declination?
step 1: get the angle of magnetic north to true north (you don't have to calculate it - it's given online...)
step 2: find out if the magnetic north is to the left or right of the true north from where you are on the earth (again, already figured out - all you have to do is look online)
step 3:
if it's to the left of true north, move the dial to the right at the angle calculated...
if it's to the right of true north, move the dial to the left at the angle calculated...
example: i live in calgary...the position of magnetic north is approx 16 degrees right of true north...therefore i just more the dial to the left 16 degrees (it will be minus because the numbers go up clockwise) - at 300. moving it 16 to the left is just moving to 284...
all the videos with complicated explanations for a simple calculation...
oh, and i have a degree in astrophysics so i understand why magnetic north behaves as it does - and it didn't help worth crap because i just overcomplicated it like everyone else...
just make it easy...
Your are so beautiful ❤️
Honestly who dislikes this
Bra I don't understand anything u saying bro like what are u saying man stop the cap bro😢
Dyu
damn that woman is gorgeous
So anoying to look at your facial expression. Sorry 😢
