34 Chapter 4: Time to Apply
Below are materials to support teaching and learning about scientific ocean drilling that connect to the content in this chapter. We also encourage you to explore the Resources for Educators page in this OER for links to additional exercises and assessments.
Time to Apply: Part A
Exercises 4.1
Exercise 4.2
The section Adjusting the Ship for Horizontal and Vertical Motion introduces the Dynamic Positioning (DP) system, a crucial technology on JOIDES Resolution that helped the ship maintain its position within a safety zone above the drilling site, whilst enduring the push and pull of the wind and current. The primary safety zone allowed the ship to drift up to 3% of the drilling depth to the seafloor, while the secondary safety zone extended to 5% of the drilling depth. If the ship moved beyond the 3% zone, alarms were triggered, and if it could not stay within the 5% zone, drilling operations were stopped.
Based on a water depth of 4300 meters, answer the following:
(a) Calculate the allowable distances for both the 3% and 5% safety zones.
(b) If the ship drifts 150 meters from the drill site, which safety zone is it within?
(c) What potential equipment or other concerns could arise if the ship moves beyond the 3% zone and outside the 5% zone?
Exercise 4.3
Safety Scenario
Exercise 4.4
At the end of the Keeping People Safe section of this chapter, view the video about lifeboats on JOIDES Resolution, and answer the following question:
Exercise 4.5
Answer these questions about the Protected Species Watch in the Keeping the Ecosystem Safe section of this chapter.
Exercise 4.6
Read through the article, Cooking Under a Midnight Sun. In addition to the information you read about Food Service in this chapter, respond to the following questions.
- In addition to serving the nutritional needs for all on board, in what ways does the food and meals provide for the mental well-being and happiness for the scientists/technicians as well as the Entier crew?
- What are the considerations the Entier crew must take into consideration when planning meals and a menu for each day, as well as throughout an expedition? (Hint: think about the varied diets of individuals, as well as food expiration dates)
Exercise 4.7
During Expedition 393 on JOIDES Resolution, a Daily Operations Report was emailed to all on board the ship. Below are two separate days worth of data regarding consumables.
(a) What is one observation you can make about fuel consumption between when the ship was drilling on July 28 (and thus was using Dynamic Positioning) versus when the ship was fully underway and heading back to port on July 31?
(b) For Lube Oil, two units are shown: USG and M³, separated by a ‘/’. Find out what each abbreviation stands for and what physical quantity these units measure.
(c) Which would have a larger amount of oil, one USG or one M³?
July 28 Consumables Data:
| Description | Units | Yesterday’s Totals | Used Today | Received, Made or Transferred | Remaining Onboard |
| Fuel | USG | 404293 | 5143 | 0 | 399150 |
| Fuel | MT | 1261.4 | 16 | 0.0 | 1245.4 |
| Lube Oil | USG/ M³ | 11753/44.5 | 16/0.1 | 0/0.0 | 11737/44.4 |
July 31 Consumables Data:
| Description | Units | Yesterday’s Totals | Used Today | Received, Made or Transferred | Remaining Onboard |
| Fuel | USG | 387386 | 10235 | 0 | 377151 |
| Fuel | MT | 1208.8 | 31.8 | 0.0 | 1177.0 |
| Lube Oil | USG/M³ | 11674/44.2 | 56/0.2 | 0/0.0 | 11618/44.0 |
Time to apply: Part B
The JOIDES Resolution website has an entire collection of Classroom Activities that include lesson plans, data exercises, digital interactives, posters, and career information. Here in Part B, we call attention to materials that relate to the content of this chapter.
- Drilling rates through oceanic crust — Students will be able to calculate drilling rates over a three-day period during Expedition 309 by using the data provided. This activity is in the For Educators section of the JOIDES Resolution website.
