With the rapid development of the global economy, the demand for energy has increased significantly over the world. However, with the depletion of traditional fossil energy and the greenhouse effect caused by the use of fossil energy, more and more countries have a strong interest in the development of low-emission and renewable green energy. Some countries have taken action to increase support for renewable energy development. Corresponding measures have also been taken worldwide, such as the Paris Agreement signed in December 2016, which has been recognized by 120 countries around the world. In September 2020, China clearly proposed the goals of “carbon peaking” in 2030 and “carbon neutrality” in 2060. Power generation using wind and solar energy has been widely used, but the utilization of marine renewable energy still needs further research. Among the many potential marine renewable energy resources, wave energy is one of the most promising energy resources owing to its high predictability, high power density and high utilization rate. Despite the abundance of the theoretical resources of wave energy, there are some uncertain factors, such as uneven spatial distribution, large seasonal and inter-annual variations, and the impact of extreme wave conditions on the wave energy converter (WEC), needed to be considered. Therefore, the premise of developing wave energy resources requires an assessment of spatial distribution and seasonal and inter-annual variations of the wave energy resources based on a long-term and reliable dataset of waves. Due to the relative lack of long-term wave observation data, numerical simulation technology has been widely used to provide a wave database.

On June 4, 1963, less than a year after the controversial environmental classic “Silent Spring” was published, its author, Rachel Carson, testified before a Senate subcommittee on pesticides. She was 56 and dying of breast cancer. She told almost no one. She’d already survived a radical mastectomy. Her pelvis was so riddled with fractures that it was nearly impossible for her to walk to her seat at the wooden table before the Congressional panel. To hide her baldness, she wore a dark brown wig. “Every once in a while in the history of mankind, a book has appeared which has substantially altered the course of history,” Senator Ernest Gruening, a Democrat from Alaska, told Carson at the time. “Silent Spring” was published 50 years ago this month. Though she did not set out to do so, Carson influenced the environmental movement as no one had since the 19th century’s most celebrated hermit, Henry David Thoreau, wrote about Walden Pond. “Silent Spring” presents a view of nature compromised by synthetic pesticides, especially DDT. Once these pesticides entered the biosphere, Carson argued, they not only killed bugs but also made their way up the food chain to threaten bird and fish populations and could eventually sicken children. Much of the data and case studies that Carson drew from weren’t new; the scientific community had known of these findings for some time, but Carson was the first to put them all together for the general public and to draw stark and far-reaching conclusions. In doing so, Carson, the citizen-scientist, spawned a revolution. “Silent Spring,” which has sold more than two million copies, made a powerful case for the idea that if humankind poisoned nature, nature would in turn poison humankind. “Our heedless and destructive acts enter into the vast cycles of the earth and in time return to bring hazard to ourselves,” she told the subcommittee. We still see the effects of unfettered human intervention through Carson’s eyes: she popularized modern ecology.
