Hi everyone and welcome to another

episode of Divers English.

Today we're going to talk about the dive site layout.

We're going to look at a little bit of

current, depth, water temperature,

everything based on the water

when you arrive at your dive site.

So without further ado,

let's get into the video!

Hi, I'm Taylor.

Hi, I'm Yumi.

Welcome to Divers English.

So, on today's episode, we're going to be

having a look at the dive site layout.

Now, usually this is very important

because it's a part of your...

Dive briefing?

Yes.

So, when you get to the dive site,

any new dive site, you'll

usually have a dive briefing

and these are very important things you

can give your students

when they arrive - in English.

Okay, so our next one we're going

to have a look at is the...

temperature and depth.

That's pretty good.

Good pronunciation.

All right, so be careful

for 'temperature' even though...

This is one of those English words where

the spelling and the

pronunciation is very different.

You need three sounds here.

All right, so it's quite easy.

All right, so for temperature,

we're going to look at a few things that is important

because if you have diving students,

at the end of the dive,

they need to fill in that logbook

and these are things they

need to fill in, in the logbook.

So, if they're confused, you need to kind

of help them with this.

So, we're going to look at the first one

which is air temperature.

Okay, this is just the general air

temperature which I don't know, they can

have a look on their phones for.

The weather application?

Yeah, the weather for your area

- the air temperature.

The first one we're going to have a look

at is the surface temperature for the water.

Yeah, so right on the

top just when you enter,

usually most watches just

record it - your dive computer.

So, they record the surface temperature

which you can show them how to find on

their dive computer.

The next one is the bottom temperature.

The sea bed?

Yes, so the bottom, the max depth

they reach, what is the temperature

reading from there?

Okay, and the next one is...

Average?

So, the average, the dive

computer also kind of

calculates this one for you.

I don't know how they get the average,

maybe surface and bottom together or

maybe air, I don't know.

I'm not so sure about how the internals

work but that's your average temperature.

So, just one more.

Two sounds.

Not av-e-rage.

So, these are your different types of

temperatures you can record.

Next, we're going to have a

look at an actual temperature.

Now, in Japan and most European countries,

they'd work on 'degrees Celsius'.

Okay, so when you switch on the weather channel,

your information you're getting

is in degrees Celsius.

Alright, so one more...

Okay, this is a tricky one.

Lots of S's here.

Yeah, there's a hidden "yuh" sound here.

Tricky to say, hey?

Alright, if you do have American

students, some of them would

work on 'degrees Fahrenheit'.

Yeah, just think of it as

the last part as 'night'.

So, day and night.

So, I'm not sure of the

calculation for Fahrenheit.

I think you can check Google for that one.

But sometimes you might need to tell

somebody it's ____ degrees Fahrenheit.

Okay, the next one we're

gonna have a look at is...

Depth.

So, your last sound here is the...

You wanna put your tongue

between your teeth.

Yeah, not too hard.

Okay, move your lip down.

Okay, so usually your ascending speed for

all divers should not

exceed 18 meters per minute.

Usually the dive computer will alert you

and start vibrating.

Slow down, slow down if

you're ascending too fast.

But maybe you wanna remind some students

when they're starting their open water or

advanced open water,

beginner divers like to kind of fly up.

So, you need to tell them

don't exceed 18 meters per minute.

Another important one here is with the meters,

Americans again work in feet.

So, not meters.

I'm not sure of the calculation.

From changing meters to feet,

you can also Google that one.

Alright, another thing we're gonna have a

look at is the general depth.

Alright, general depth is

how deep you are diving.

Normally for your dive computer it will

record the maximum depth,

which you can check in your

dive log from your dive computer,

which they'd also need to

fill in to their diver's log -

Logbook.

Yeah, that's usually it

from temperature and depth.

Alright, let's move on to the next one.

Okay, so the last parts we're gonna be

looking at is two of our topics.

Current and... tide.

Our current and tide.

Now, usually you want to explain,

generally this is also another important

part of the dive briefing.

Because you want to tell your students if

there's current or not.

So, when they dive in it's

not like surprise, bye bye.

Alright, so obviously there are three

main types of currents you want to be

telling the students about.

Either no current, okay.

Mild current.

Strong current.

Okay, so obviously mild current is the mild pull.

And then strong current, a stronger current.

Okay, also depending on the dive area,

you want to tell your students about the

two types of currents,

if there are (any) in that area.

The upwellings.

Upwellings are generally currents that

come from the bottom of the

ocean coming through the...

coming above or coming towards the

surface of the ocean.

That is an upwelling.

Generally, it's good for fish because

they can get foods from

the bottom of the ocean.

So, that's an upwelling.

Alright, but generally it's called the

water in upwellings.

Alright, then we've got downwellings,

which is usually sometimes

on inclines of the water.

With the sea bed having an incline,

it can create a down pull.

Yeah, it's a very dangerous thing because

you can get pulled very fast, very deep.

But obviously, most divers tend to stay

away from downwellings.

Although, be careful of that one.

If there is any, or if there's a chance of any,

you want to be warning your

Alright, the next one we're

going to have a look at is our...

Tide.

Alright, so, Tide, we

actually have our tidal currents.

Sometimes you want to explain to your

students a bit of the theory behind currents.

So, a tidal current is the tide that

comes in and goes out,

just pulls this ocean forward and back.

And this is generally the

gravitational pull of the moon.

So, as the moon rotates around the earth,

the sea gets pulled

towards that direction.

That is a tidal current.

Alright, when you're

explaining tides to your students,

sometimes you want to explain to them

between low tide and high tide,

a lot of instructors have an application.

To show when it's low tide or high tide.

And obviously, everyone

knows the best time to dive is...

Slack tide.

Slack tide, yeah.

That's when it's neither pulling or

pushing, it's just on a level.

There's two levels.

So, when a tide comes in, the maximum

day, and when a tide

goes out, the maximum day,

those two points are

the best time to dive.

We call it slack tide.

Alright.

And that's mostly tides and currents.

Alright, let's move on.

Okay, so we hope you enjoyed our video

today about the dive site layout.

And we hope you learned some new

vocabularies that you can utilize when

teaching your English students.

As this is part of the dive briefing,

every instructor teaching English

students has to know these words.

So, it's very important to explain them.

As well as, like I said,

when the divers go home,

they need to fill in their

logbook before they leave.

And a lot of those things are...

Students might ask, "Why? Why is this

happening? Why is this?"

I know I asked why so many times.

So, my instructor had to explain.

And yeah, so it's very important.

But anyways, we hope you enjoyed the

video and picked up some new vocab.

And we will see you on the next one.

Yeah.

Alright.

Take care. Bye-bye.
