As a newcomer to hardware, I have received a hydrophone (TC4013 - photo attached) to collect response data and intend to purchase an amplifier for this purpose. However, I am uncertain about how to connect these components to the Arduino board and whether any additional components are required. Could anyone please advise me on this matter?
Welcome! What is the question. From what I see with the information you have given I do not think you will be successful. It appears the output is RF and the Arduino's are not capable of that as a standard digital input. I believe you will need some type of analog to digital interface. Show a preliminary schematic as to how this is to go together, also some of your work on how they are to interconnect and what you expect as an output.

Please describe what you mean by "collect response data".
Most Arduinos aren't capable of doing much with ordinary audio, that is, within the range of human hearing. They don't have the speed or memory.
Laptops and advanced single board computers like the Raspberry Pi are better equipped for capturing and recording audio, but you will need special equipment to process and store audio signals above the range of human hearing.

Well, please do not feel alone, I surely cannot figure it out, either!
Pulling the PDF does not give me any hint on what "value" Arduino would play in the system:

My project aims to locate the location of a pinger and direct the surface vehicle towards it. I am not sure what I meant by "collect response", I only know that I need some sort of response to determine the time difference of arrival of the signal at multiple hydrophones placed at known positions. (I am very new to signals, hardware, and software. Quite lost as to where to begin.)
Thank you for your help!
That is quite a challenge! The topic of sound source localization comes up all the time on this forum, and never goes anywhere. Arduinos are simply too limited to monitor several microphones at a time.
On the other hand, a LOT of research has been put into the problem. Good search keywords are "time difference of arrival" "trilateration" "sound source localization", etc.

By amplifying and recording these electrical signals, hydrophones measure ocean sounds with great precision. While a single hydrophone can record sounds from any direction, several hydrophones simultaneously positioned in an array, often thousands of miles apart, result in signals that can be manipulated to “listen” with greater sensitivity than a single device. Omni-directional and hemi-directional hydrophones pick up sound from a particular direction and can be used to track fish movements.
What is a hydrophone? (noaa.gov)
With only 1 hydrophone, the location process is more complex.

I would suggest you look at some amature radio sites and also look there for FOX hunt. It is not exactly what you are asking for but it is similar.
The devices you linked to are strictly AUDIO, up to 1 mHz audio. I cannot conceive of anything an Arduino of any type that would be able to do anything with that range of audio signal. What actual audio frequencies are you interested in?
From my previous (lite) research to arrive at my previous post, these devices are broadband primarily to ensure a flat frequency response underwater. In actuality, actual hydrophones in-use, have a much more narrow characteristic:
The Ops's possible intent is to utilize a uC to create a directional map to an underwater sounder; many research papers exist on the math utilized which is complex... notebook computing power likely required.
In my search, I found various articles referencing Arduino + hydrophone, but all were geared toward underwater sounds and not direction finding.
