Q

How did we do stone sampling?

A

Collected 10 stones in a 1m² area every 250m - data reliable we can get an average
Used a random number generator to collect rocks to remove bias

Q

How did we do clinometer readings?

A

Person A stood on the shoreline facing the cliff
Person B stood 10m away
Clinometer measured the gradient
Person A moves to where person B was standing
The process is repeated 5 times 250m apart

Q

What types of sampling methods were used for clinometer readings?

A

Systematic - data collected 5 times for 250m
Stratified -repeated 5 times so we can see a change in data

Q

How did we do sediment sampling?

A

We used two 1 metre sticks
Random number generator to select two numbers
Measured the longest side - a-axis
Measured the width - b-axis

14
Q

How did we use geology maps?

A

It relates the type of the rock to the features found or the processes we are likely to see

Q

How did we use ARC GIS?

A

We looked at Sewerby beach and Hornsea before
So we can compare before and after of the shape of the beach - chalk was carried down and more rocks at site 1 than 4 +5

Q

What were the limitations of qualitative data collection?

A

Pictures only taken at one place - can’t make a comparison
Pictures taken same time- can’t make a comparison of change over time

16
Q

What were limitations of secondary data collection?

A

Geology maps give a generalised picture - can’t see fine detail
Don’t know what measuring instruments were used and the amount of training they had - difficult to accurately compared data

16
Q

What did we do to gather qualitative data?

A

We annotated a picture

16
Q

What were the limitations of quantitative data collection?

A

Tide was in - less of angle to measure on the clinometer
Rock sphericity is subjective
Chose a small section if the beach - don’t get the full picture + unintentional bias

16
Q

How did we annotate a picture?

A

Boulder clay at a gentler angle than chalk (boulder clay is softer)
Chalk sediment on beach due to hydraulic action and abrasion

17
Q

What are the pro’s and con’s of using scatter graphs to present data?

A

Need to manipulate data (averages) - helps to analyse results and spot patterns
Compares all sites
Helps answer the main question

18
Q

What are the pro’s and con’s of using box + whisker plots to present data?

A

Need to manipulate data (median + IQR) - helps to analyse results and spot patterns

19
Q

What are the pro’s and con’s of using beach profiles to present data?

A

Data presentation method
Simple to complete
Compares all sites

20
Q

What are the pro’s and con’s of using annotated field-sketches/ pictures to present data?

A

Qualitative data presentation
Allows several observations + explanations to be pulled together
Provide explanations for quantitative data results

21
Q

What are the pro’s and con’s of using ARC GIS graphs to present data?

A

GP’s located graphs
Able to see trends on the coast on a map or satellite image

22
Q

What were the main conclusions made?

A

Beach got wider as more angles were recorded further down the beach
Median rock size increased going down the beach
Chalk deposited along the beach as far as South Hornsea whilst white chalk cliffs end on Sewerby beach

23
Q

How did ICT help with this project?

A

Used Survey 123 and GPs to record where we measured data

24
Q

How could we use ICT further in this project?

A

Finding secondary research/data e.g. Hull university share a lot of data about the Holderness coastline

25
Q

What were the pro’s of beach profiles?

A

Easy to collect data
Systematic sampling allowed us to cover a large sample area quickly

26
Q

What were some risks and how do we manage them?

A

Slips, trips and falls - wear appropriate footwear, take care on slippy rocks, teachers have first aid
People drowning - no one is allowed in the water
Sunburn or Hypothermia - check weather forecast, wear appropriate clothing

27
Q

What were the con’s with beach profiles?

A

Not always accurate as people sunk into wet sand
Two people weren’t always the same height

28
Q

How could we improve beach profiles?

A

Use better equipment like Dumpy Level + Staff

29
Q

What were the pro’s of sediment sampling?

A

Simple method
Systematic sampling covers a large sample area quickly
Random number generator removes bias

30
Q

What were the con’s of sediment sampling?

A

Measured to the nearest cm
Only done once
Sphericity is subjective

30
Q

How could we improve sediment sampling?

A

Measure to the nearest mm
Repeat this in different times of year, month, day

31
Q

What were the pro’s of our results?

A

Easy to compare graphs

32
Q

What were the con’s of our results?

A

Not accurate as human error can occur in data manipulation

33
Q

How could we improve our results?

A

Using excel would improve data presentation methods

34
Q

What were the pro’s of ARC GIS?

A

Graph made at specific GPs points along the coast
Showed clear trends of stones getting smaller

35
Q

What were the con’s of ARC GIS?

A

Stone sizes were too big
Harder to see trends for sphericity of stones
