Thank you, Brittany. Good morning, and welcome to Geospace Technologies conference call for the second quarter of our 2021 fiscal year. I'm Rick Wheeler, the company's President and Chief Executive Officer and I'm joined by Robert Curda, the company's Chief Financial Officer and also with us this morning is Dr. Mark Tinker, CEO of our Quantum Technology Sciences subsidiary. I'll first give an overview of the second quarter and Robert will follow with an in-depth commentary on our financial performance. After a few last remarks, we'll open the line for questions that hopefully Robert, Mark and I can answer.

As a convenience, we will link a recording of this call on the Investor Relations page of our geospace.com website and I encourage everyone to visit and browse that site to learn more about Geospace and its products. Note, that the information discussed and recorded this morning is time-sensitive and may not be accurate at the time one listens to the replay. Yesterday, after the market closed, we released financial results for our second quarter of fiscal year 2021 which ended March 31, 2021. Just as the COVID-19 play worsened in some locations, while improving in others, our business segments reflected similar divergence in the second fiscal quarter. Yet, despite the challenges, the pandemic has thrust upon us. There are signs of recovery for the overall economy as well as the businesses we serve. In many places, COVID-19 restrictions are being lifted. Air travel is ramping up and businesses are reopening and returning to work. Nonetheless, the pandemic's severe impact is evidenced in the three and six month periods ended March 31, 2021. In our oil and gas market segment, gaps in demand for our OBX marine nodal systems continued through the second quarter. This led to much lower rental revenue throughout the first six months of the fiscal year compared to last year. Moreover, as earlier OBX rental contracts ran to completion, many of the planned contracts for follow-on work and new surveys could not be started due to COVID-19 lockdowns and travel restrictions. In constellation, we believe much of this work will resume as COVID-19 vaccines are broadly distributed and recovery from the pandemic gains momentum. Even now, request for quotes on future OBX system rentals have increased and some new contracts are already underway or about to begin.
