The proposed study will conduct several magnetic lines across the Cretaceous Quiet Zone (KQZ) seafloor in the south Pacific between Samoa and New Zealand. Magnetic data will be collected by a ship and with an autonomous aerial vehicle (AAV) will be launched and recovered from the ship to cover a swath of magnetic lines. The objective is to collect closely spaced magnetic tracks that will show correlatable magnetic anomalies within the KQZ. The ship's magnetic gradiometer will allow external field variations to be quantified and removed from the data. Vector magnetic data will also be collected to define the three-dimensionality of the magnetic anomalies. The data will allow the determination of the nature of the magnetic anomalies in the KQZ and reveal more about magnetic field behavior and/or crustal accretion processes. Broader impacts include the potential of clarification of a long-standing issue concerning the higher resolution details of the Cretaceous Magnetic Quiet Zone. Graduate students will be involved at both institutions.

拟议的研究将在萨摩亚和新西兰之间南太平洋的白垩纪安静区（KQZ）海底进行几条磁线。磁性数据将由船舶收集，并使用自动驾驶汽车（AAV）收集磁数据，并将从船上发射并回收以覆盖一条磁线。目的是收集距离紧密间隔的磁轨道，这些轨道将在KQZ内显示可相关的磁异常。该船的磁性梯度计将允许量化外部场变化并从数据中删除。还将收集向量磁数据以定义磁异常的三维性。数据将允许确定KQZ中磁异常的性质，并更多地揭示有关磁场行为和/或地壳积聚过程的更多信息。 更广泛的影响包括澄清长期存在的有关白垩纪磁性安静区域的更高分辨率细节的潜力。研究生将参与这两个机构。
